To most people, Piper Sail looks like a rich girl with little potential, but she surprises everyone, including herself, when she starts investigating her best friend’s disappearance. Perfect for fans of Agatha Christie and Maureen Johnson, The Lost Girl of Astor Street combines the allure of Jazz Age Chicago with a twisting mystery that will keep you guessing until the very end.

Lydia has vanished. Lydia, who’s never broken any rules, except falling in love with the wrong boy. Lydia, who’s been Piper’s best friend since they were children. Lydia, who never even said goodbye.

Convinced the police are looking in all the wrong places, eighteen-year-old Piper Sail begins her own investigation into Lydia’s disappearance. With the reluctant help of a handsome young detective, Piper searches for answers in the dark underbelly of 1924 Chicago. Did Lydia get abducted by one of the city’s most notorious gangsters? Or does the trail lead back to their own affluent neighborhood?

“Morrill has a keen eye for historical details and setting, making Jazz Age Chicago Piper’s invisible yet omnipresent sidekick. A…well-crafted historical whodunit.” —Kirkus Reviews

Piper must decide if she’s willing to risk her life to find out the truth.
