My Readers Guide to The Intruder discusses this new book by VERY prolific and popular thriller author Freida McFadden. I’ve loved books like The Housemaid and The Wife Upstairs but found some of her latest books (like The Teacher and The Boyfriend a bit disappointing. What did I think of this new book about a woman alone in a storm… or is she?

Jen’s Quick Take on The Intruder

- The Intruder has a past/present narrative and VERY short (like three page) chapters
- Casey, the main character in the present narrative, is trapped in her cabin in a storm
- In the “before” narrative, eighth grader Ella struggles with her mom’s hoarding and abuse.
- When a young girl turns up in Casey’s shed, who is she and what does she want?
- I struggled with this one. It had a slow pace. I really disliked the super short chapters. Casey’s thoughts and actions often made no sense. There was a lot of repetition. And based on McFadden’s prior books, I could guess one twist.
- On the positive side, I thought Ella’s chapters were much stronger.
- Content warning: while the Author’s Note says this book has no explicit violence, it’s a pretty dark book. With violent acts!
- Publication date: October 7, 2025 by Poisoned Pen Press.
- Nominated for a Goodreads Choice Award in 2025

Plot Summary for The Intruder

With three page chapters that alternate from past to present, this summary might be too choppy unless I do a present day summary and a past day summary, and connect them when they converge. I’ll do the past first. Please leave any and all questions and correction in the comments!
