Lisa Jewell’s Don’t Let Him In is for anyone who’s ever side-eyed a man who seems just a little too smooth. The book follows Nick Radcliffe (or whatever name he’s using today), a serial husband who collects wives the way other people collect frequent flyer miles. Enter Ash, whose mom has fallen for him, and who immediately clocks him as a walking red flag with a bank-draining hobby. As Ash digs into his past, the story flips between her detective work and Nick’s own delusional internal monologue where he’s somehow the hero. It’s gripping, twisty, and just messy enough to feel real. Take the book’s advice: if you meet a man who seems perfect? Don’t let him in.
