Thank you to NetGalley for this ARC in exchange for an honest review. An intriguing story that literally kept me up at night. A perfect read for a cool, dark, October evening.

Thank you to Poisoned Pen Press, Sourcebooks, and Netgalley for the advanced reading copy!

This one had a lot of potential but unfortunately fell short for me. I listened to most of it and was so engrossed and freaked out by the first 1/2 of the book. The author does a great job of keeping you on your toes about the twins as well as their new friend. Then the last 1/2 of the book it just ended. I was left feeling unfulfilled with the resolution / the ending of the book.

I’ve been on the fence about my feelings about this one. What I liked- Grief horror, meets psychological horror, meets creepy imaginary friend. I love a spooky kid and an imaginary one takes this eerie trope to the next level. I loved the atmosphere of claustrophobic horror that is created here. - So effective. I loved the perfectly ambiguous ending that lets your mind go to all the dark possibilities. That is always terrifying to me. What I didn’t love was how it started. It was too slow and took way too long to go anywhere and I almost quit reading it numerous times. Once things did start happening it was great, but it took almost half the book to get to that point. . Overall, this was a mixed bag for me. Thank you to @netgalley and @poisonedpenpress for an e-arc of this book.

Creepy and insidious - is he real? Imaginary? A ghost? or something worse? And what energy is making him stronger? As the entity strengthens and takes hold more and more - some real truths will need to be revealed if they have a chance in the fight. Who will win? If you like creepy "haunted house, imaginary friend" vibes - this is for you

This book gave me all the right creepy vibes.. I was genuinely on edge and felt the heeby jeebys. It was a quick, easy read

Delightfully eerie, twisted and guaranteed to keep you up all night! There were so many twists and turns, the characters are well developed and the plot was incredibly creepy.

After a slow start to the book I wasn’t sure if I wanted to continue but after reading in for a while i was hooked and couldn’t out the book down! Never in my life have I ever experienced heart pounding fear that consumed me until the very last words. Let Him In, is a fear gripping book and if you can get past the first half of the book you will not be sorry!

A gem of an audiobook with excellent narration. Hart House is not a place of fond memories for many members of this family; this becomes abundantly apparent in the most recent generation, when twin girls start speaking of a "friend" who visits, which none of the adults can see. Calling on their Aunt Julia, a psychiatrist, to help get to the bottom of the situation, Alfie, their dad is hopeful it will soon be over. Deep generational scars are tough to heal, though.

I was just too slow for me. I kept reading expecting things to move on and something to happen, but it was only at the very end, I think the second-to-last chapter, but by then all the interest was just... I liked the premise, the idea, and the characters had so much potential, but there was hardly anything happening.

I jumped at the chance to read this one based on the description. It seemed like a heart-racing horror novel based off the description. Unfortunately, this ended up being a super boring read! I gave up reading at 36%. just could not finish this one. In the first third of the book, nothing remotely scary happened. I felt the writing was all over the place and messy. It was hard to follow. It felt like a chore to read, which is why I stopped.

This started off pretty eerie! Twin girls that have an imaginary friend that takes form of a black mamba snake after their mother dies. I hate snakes so this was very creepy, especially after googling what a black mamba looks like, lol!

Great for spooky season, but slightly underwhelming ending.

This book really just took me for a ride. I loved the build up, the character development, and the writing. I would definitely read more from this author!

Book starts off quite slow for me, but gives a view into how grief is handled in the family. The writing style is not particular for me, but it was an interesting read.

Such an amazing read! I would definitely recommend it to anyone looking for a good slow burn psychological suspense!!

This was an ok book. I think my issue is that I expected it to be a horror book vs suspense. It wasn't scary at all. It mostly focused on grief and how everyone handles it differently. I didn't truly connect with any of the characters, which is a big thing for me.

Maybe if I would've gone into the book knowing this it wouldn't have clouded my judgement. Nevertheless, it was an ok read and I'm not mad I read it.

An unnerving tale reminiscent of Turn of the Screw and others that involve "possessed" and haunted children. Chapters alternate between the twins recently bereaved father and aunt, as the history of both the family and the house is revealed.

Gets wrapped up a little too neatly, but an enjoyable, almost gothic, read.

Thanks to NetGalley and the publishers for this e-copy.

This book was the perfect read during the Halloween/spooky season! I loved it. It kept me on my toes and was unpredictable! The setting is perfect, in a falling down house called Hart House with peeling walls and a winding staircase. It’s just the type of house you’d picture a horror movie would take place in.

"Let Him In" was an enjoyable read. It wasn't really scary, but it kept you guessing about what was going to happen. I feel like the author took his time with the ending building up the suspense, and I liked how ending was written. The way the author wrote the story kind of reminded me of the old time radio shows.
This book would be good if you enjoy paranormal stories that aren't too scary.

I thought this book was pretty good. I had trouble reading it from the start but I thought I’d give it several more chapters thinking it would get better with the story line. As I continued to read, I found the author had done a great job with the plot and it turned out to be a good book by the end.

Let Him In is a perfect book to pick up if you are looking for a spooky read with themes of grief. There is also a strong focus on the relationship between the main character and his daughters, which I really liked. Overall, I would recommend this book to readers who like a good haunted house story with rich thematic content.

Thank you to the publisher and to Netgalley for granting me an e-ARC in exchange for an honest review.
