I finished The Boyfriend and immediately picked up The Intruder by Freida McFadden. That should tell you something right there. When an author keeps pulling you back for more, you just go with it. This one is a psychological thriller, but it has a different energy than some of her other books. Honestly, I found that refreshing.

Two Women, Two Very Different Lives

The story is told in two timelines. In the “Before” sections, we follow Ella, a 13-year-old girl living with her mother in a house packed with junk. Her mother is a hoarder. Ella tries to clean up, but every attempt ends in a fight. It’s a quietly heartbreaking situation. Meanwhile, in the “Now” sections, we meet Casey, a woman living alone in a remote cabin after losing her teaching job. A major storm is coming, and Casey is preparing to ride it out without power.

From early on, I suspected that Casey was Ella, grown up. The contrast between the two women made it feel almost certain. Ella lives in chaos she can’t control. Casey’s cabin is neat and organized. After leaving her mother’s house, it seemed like Ella finally had the freedom to live exactly the way she wanted.

The Men on the Edges of the Story

Two men are introduced early in Casey’s timeline, and they both felt potentially dangerous. Her landlord, Rudy, flirts with her constantly and keeps putting off fixing her leaking roof, storm or no storm. Then there’s Lee, a neighbor about a half mile away through a path in the woods. He checks in on Casey occasionally, but she doesn’t know him well.

I kept waiting for one of them to become a serious threat. Casey is completely alone out there, and a major storm is about to cut her off from help. That setup had me bracing for something. However, as the story unfolded, both Rudy and Lee ended up playing a fairly small role. That was probably my biggest disappointment with this book. The author set up what felt like real danger, but didn’t fully deliver on it.

When Eleanor Shows Up

The moment that changes everything is when Eleanor appears in Casey’s shed. She’s a girl, maybe 12 or 13 years old, and she has a knife. There’s blood on her clothes. Something inside her bag is dripping. Casey is terrified, but she lets Eleanor inside anyway.

This is where the psychological tension really kicks in. Casey doesn’t know if this girl has killed someone. She doesn’t know if she herself is in danger. Furthermore, we as readers are left wondering the same thing: Is Eleanor actually Ella? Their stories are so similar. Both grew up without knowing their fathers. Both even had the same green lighter. That detail especially stood out to me.

More Drama Than Thriller

The Intruder leans more toward drama than a straight thriller. There are no graphic murder scenes here, no detailed descriptions of violence. I actually appreciated that. In my review of The Boyfriend, I mentioned how McFadden builds dread through perspective and pacing. This book does something similar, but in a quieter way. The tension comes from not knowing who to trust and from watching two stories slowly converge.

That said, if you’re coming in expecting the same level of suspense as some of her other work, you might find this one feels a bit restrained.

Where the Story Stumbles

My main issue was with how the connection between Ella and Eleanor was handled. Their similarities are almost too perfectly mirrored, right down to the green lighter. Then, near the end, it felt like the author had to manufacture differences specifically to show they were not the same person. It came across as a little forced. For a story that spent so much time building toward that question, the resolution didn’t feel entirely earned.

Final Thoughts

Overall, I liked The Intruder. It’s a slower burn than some of McFadden’s other books, but the dual storyline kept me engaged, and Ella’s sections especially stayed with me. The hoarding, the longing for a father she never knew, the way she kept imagining how different her life might have been: all of that felt real and affecting.

If you’re a McFadden fan, this is still worth reading. Just go in knowing it’s more of an emotional drama wrapped in a thriller frame than a straight edge-of-your-seat suspense read. And if you haven’t read The Boyfriend yet, I’d start there first.
