It's been a while since I've read this book, and with book two on the horizon, I wanted to give this a reread before I dove into book two. And my goodness, it was even better than I remembered it! I adore Piper and Lydia and Mariano and was brought to tears several times by Piper's staunchness in finding her friend. She would do anything for Lydia and isn't afraid to do things that many girls her age (or her status) would even think of doing. Mariano's support of her, his kindness and assistance, all green flags for me! It was honestly so refreshing to read a mystery that is twisty and had me on the edge of my seat (again, I'd even read it before!) without the explicit language or scenes. Morrill is a master mystery writer and I hope for even more Piper Sail books!

This was a fun cozy mystery! This one was the perfect amount of intrigue with such lovable characters! Of course as the reader you get frustrated with the "amateur" making decisions that aren't smart, but I loved that she had sensible people in her life. For a time you didn't know who the love interest would be which was fun. It was overall so much fun and I want to read more from this author.

Set in the 1920s, The Lost Girl of Astor Street is an Agatha Christie-esque mystery with Piper Sail, a spunky 18 year old, as the sleuth. When her best friend, Lydia, goes missing, Piper uses all of her wits and cunning to find out what happened. No one is who they seem to be in this book. There are all sorts of twists and turns leading to the dramatic conclusion. This book is perfect for anyone who likes amateur detective stories sprinkled with a little romance and danger.

I received an advance reader copy. All opinions are my own.

A richly atmospheric historical mystery set in 1920s Chicago, The Lost Girl of Astor Street swept me away with its compelling blend of intrigue, vivid setting, and a fiercely determined heroine. Piper Sail is smart, bold, and refreshingly ahead of her time as she searches for her missing best friend amidst secrets, danger, and the shadowy world of organized crime.

Stephanie Morrill brings the Roaring Twenties to life with sharp detail—from opulent mansions to smoky speakeasies—while weaving a twisty, satisfying mystery that kept me hooked. I loved the balance of suspense, subtle romance, and themes of friendship and courage.

Piper and Lydia are neighbors & best friends nearing the end of their senior year of high school. They grew up together and Lydia's parents are a bit more "proper" and expect a bit more from Piper - often times having Piper think she's a bad influence on Lydia with their antics. But Lydia's parents are keeping a secret from Lydia, and have sworn Piper to secrecy - once the secret comes out, Lydia comes to say goodbye to Piper (she's leaving town for a bit), but after she leaves Piper's front walk way in Piper's coat, she goes missing.

This simply will not do for Piper, who makes it her job, safety be damned, to find out what happened to her best friend. Was she taken, if so by whom? Did she leave on her own? Was Lydia mistaken for Piper?

She meets friends and foes along the way, decides dogs and babies aren't as scary as she once thought, and learns a bit about herself as well. It's always great to see characters grow.

I'm so pleased that this is the first in a series, I'm very much looking forward to spending more time with Piper and Sidekick (and Mariano).

Not giving this a public rating as I found the book was not for me. It's incredibly slow in the open and by the time things started happening I wasn't feeling it. It has a lot of love, so I've just rated this a NFM read. Thank you for the opportunity.

Oh man, it's forcing a star review - so sorry.

Piper Sail is due to graduate soon but has no real idea what she wants to do next. She shares everything with Lydia, who lives three houses down on the affluent Astor Street, but then discovers her best friend has a big secret of her own! When Lydia vanishes after leaving Piper’s home everyone is worried but she has never been able to sit and do nothing and almost before she realises it Piper is investigating and getting to know one of the detectives assigned to Lydia’s case. With everyone keeping secrets and the name of a notorious Chicago gangster keep appearing Piper is determined to find Lydia and make everything return to normal.  This is Chicago in the 1920's however, and nothing is going to be normal ever again.

Originally published in 2017 this is re-released to coincide with the second in what could easily become a must read young adult mystery series with a great main protagonist in Piper Sail. Red herrings abound with numerous possible reasons for Lydia’s disappearance alongside family secrets, romance, gangland rivalry, and even a shaggy dog story to keep the reader entertained in a most satisfactory manner.

I was able to read an advanced copy of this thanks to NetGalley and the publishers, Blink, but the opinions expressed are my own. I thoroughly enjoyed this and look forward to reading book two very soon.

I didn’t enjoy this book, all a bit twee really, was an 18-year-old girl in the American 1920’s really going the disappearance of her friend and then of course there had to be the handsome young men and the faithful dog!! Not for me and I couldn’t recommend. My thanks to Net Galley and the author for an ARC.

I absolutely loved this cozy little mystery novel. I really loved that it was set in Chicago during Prohibition and that we got to see what life was like during the 1920s. I really enjoyed Piper's character and I really felt for her when she learned that her father was getting remarried and then her best friend went missing. I enjoyed watching her overcome her fear of dogs and learning to live her life without her mom.

I enjoyed this mystery and the journey back in time! I look forward to reading the next book in the series!

1920s mystery featuring 18 year old Piper Sail, whose best friend Lydia DeVine goes missing in Chicago. In the course of investigating, Piper meets and starts dating young detective Mariano Cassino, makes new friends, and gains an unwelcome step mother. And she also learns that maybe not all kids and dogs are to be avoided…

A decent mystery and characters, this is a good introduction to a new series. Piper starts off a little prickly but thankfully warms up a bit and isn’t too afraid to grow as a person (see above with gaining a new dog called Sidekick and spending time with a young neighbour kid). I’ve got the second book in the series so I look forward to more of her adventures with Mariano!

I received a free ARC copy of this via NetGalley and the publishers in return for an unbiased review.

Stephanie Morrill’s Lost Girl of Astor Street is charming enough, but could use another edit or two to really come together. Tonally, it hits at middle grade, with its seemingly young characters and the lack of serious consequences for their actions. In addition, the characters all act quite a bit younger than their supposed ages of 18-25 - I would have pegged them at mid to early teens based on their behavior- but they all have careers that are more advanced than they should be, leading the whole thing to feel a bit like Bugsy Malone, the 80s gangster movie cast entirely with children. We’re told over and over again how smart the main character is, but the plot (and the conflict) requires her to be quite unobservant and naive, which again - would work if she was 14 or 15, but not for the age she actually is. Secondary characters are numerous and poorly differentiated. The main love interest is sweet, but again - far too young to have the career that he does. I was intrigued by the 20s Prohibition setting, but the plot and characters seem far too modern for the time period.

I can see how a young tween would enjoy this though, and there are good examples of strong female and male friendships throughout the book.

Coming of age mystery novel. Set in 1924 Chicago, Piper an inquisitive and energetic eighteen year old daughter of an attorney who defends criminal types, finds herself in a death and life situation. Her BFF, Lydia, a naive but sweet young woman has an epileptic fit right in front of Piper. Soon after, Lydia is hijacked off the street. Piper is determined to find out what happened over the objections of her father. Before she can find anything out Lydia's body is pulled out of a river. Though crushed, Piper is more determined than ever to find the killer. Heedless of the possible consequences she is determined.

As she does her best to investigate she catches the eye of a young Chicago detective who becomes very protective of this young headstrong woman who appears deaf to his appeals to let the police do their job.

The story is compelling and the pacing keeps the reader interested and curious about what twist or turn will occur next. The nascent romantic connection also keeps the reader guessing.

The tension and action rises to a peak as the story races to a conclusion. All in all, a book that any mystery enthusiast will enjoy.

Really enjoyed the 1920s setting, which was really well fleshed out with the tiny details, from the cars to the outfits to the language used by the characters. The romance was really cute, and the mystery actually had me guessing through most of the book!

The Lost Girl of Astor Street by Stephanie Morrill is a dazzling historical mystery that transports readers to the roaring 1920s, where the glitz of Chicago’s elite collides with the shadowy underworld of gangsters and corruption. The novel follows eighteen-year-old Piper Sail, a young woman who defies the expectations of her privileged upbringing to solve the disappearance of her best friend, Lydia. What begins as a desperate search for answers quickly spirals into a dangerous investigation that uncovers secrets Piper never imagined.

When Lydia vanishes without a trace, Piper refuses to believe her friend would simply run away. Convinced the police are looking in the wrong places, Piper takes matters into her own hands, teaming up with a reluctant but handsome young detective to navigate the dark underbelly of 1924 Chicago. From speakeasies to opulent mansions, Piper’s quest leads her through a maze of clues, where gangsters, corrupt officials, and even her own affluent neighbourhood may hold the key to Lydia’s fate.

Morrill masterfully captures the atmosphere of the Jazz Age, blending the allure of flapper dresses and glittering parties with the grit of Prohibition-era crime. The vivid setting serves as more than just a backdrop—it becomes a character in its own right, shaping the story’s tension and stakes. Piper’s journey is both a thrilling mystery and a coming-of-age tale, as she grapples with her own identity, societal expectations, and the lengths she’s willing to go to for the people she loves.

The novel’s strength lies in its well-drawn characters, particularly Piper, who is both relatable and inspiring. Her determination, intelligence, and vulnerability make her a compelling protagonist, while the supporting cast—from the enigmatic detective to the morally ambiguous figures she encounters—adds depth and intrigue to the story. The mystery itself is tightly plotted, with twists and turns that keep readers guessing until the very end.

At its heart, The Lost Girl of Astor Street is a story about friendship, courage, and the search for truth in a world full of deception. Morrill balances the suspense of the mystery with moments of emotional resonance, creating a narrative that is as heartfelt as it is thrilling. Perfect for fans of Agatha Christie and Maureen Johnson, this novel is a must-read for anyone who loves historical fiction, gripping mysteries, and strong, unforgettable heroines.

I found the first few chapters a little slow, but it soon captured my attention and I was eager to find out what happened to Lydia. The main character, Piper is likeable and relatable. I enjoyed the historical aspect of this novel being set in the 1920’s and the writing style was easy to read.
I liked the fact the author made it difficult to work out the villain in this story and made you not know who to trust.

This was a lovely enjoyable romp. I haven't read many stories set in the prohibition era, but its a fun place to set a mystery in.

Piper was an enjoyable main character. Yes she was brash and impulsive but she was properly motivated and by and large, she made intelligent choices. She is independent, determined and loyal to a fault. The main lead was lovely, and my heart melted a little with every scene he was in. The best character though, by far, was Sidekick. And the fact she named her dog 'sidekick', its just wonderful. Sweet without being sickly so, as the grief she felt over the death of her mother pre start of the novel and the mystery itself, ensured that there was a good balance between emotions.

The resolution to the mystery itself was perhaps the weakest part, as she didn't so much solve it, as it solved itself, but the drama of those last few chapters was very high and very good. The writing made the story easy to follow, and inspired me to keep going, to the extent that I finished this book in one day. I like Piper Sail a lot, and am looking forward to more adventures in her world. And with her boy.
