Sometimes, it’s hard to categorize a book into just one genre. Looker isn’t exactly a thriller or a mystery, but it contains elements of both. It offers a peek into the mind of an unnamed woman growing more and more unstable by the page. As she mourns her own broken life, she becomes obsessed with her neighbor, a famous actress. While Looker is short—less than 200 pages—it’s packed with themes of obsession, jealousy, and madness. Laura Sims made every word count.
