The Mystery and Thriller Books That Completely Took Over My Summer Reading
Hi Besties, I know summer is usually associated with lighthearted beach reads, but honestly? Some of my favorite summer reading experiences are the books that make me suspicious of every character, emotionally unstable by chapter twelve, and incapable of putting the book down at a reasonable hour. And this year’s mystery and thriller books for the guide absolutely delivered that experience for me. What I loved most about this lineup is how different these books feel from each other. Some are dark and psychological. Some are literary and emotionally layered. Some are sharp domestic thrillers full of secrets and manipulation. Some are twisty and addictive in that “accidentally stayed up until 2 a.m.” kind of way. These are the books I genuinely loved reading for The 2026 Summer Reading Guide and immediately wanted to recommend the second I finished them.
