The 2026 Summer “Must-Reads”
1. Helpless by Jessica Knoll (Releasing July 7)
Following her massive success with Bright Young Women, Knoll returns with a terrifying premise. A woman reconnects with a college boyfriend at a funeral, only to find herself held captive in a remote cabin. It’s a claustrophobic, high-stakes study of obsession that will make you rethink that “peaceful” cabin rental.
2. Getting Away With Murder by Shari Lapena (Releasing July 16)
The master of the domestic thriller is back. This story follows a dysfunctional family in a Brooklyn brownstone who plot to kill a wealthy relative to save their high-flying lifestyle. With Lapena’s signature red herrings, you won’t know who to trust until the final page.
3. The Ending Writes Itself by Evelyn Clarke
Imagine six authors trapped on a private island with 72 hours to finish a dead genius’s masterpiece. This debut mystery is being hailed as Knives Out meets Agatha Christie. It’s the perfect “locked-room” puzzle for readers who love a meta-narrative about the publishing world itself.
4. Hot Girl Murder Club by Ashley Winstead (Releasing July 14)
If you want something with a bit of “buzzy” energy, this is it. It’s a sharp, bloody thriller about sisterhood, fame, and a group of women demanding justice by any means necessary. It’s fast-paced, modern, and incredibly satisfying.
5. The Storm by Rachel Hawkins
Set in a Gulf Coast beach motel, this Southern gothic suspense uses hurricane season as its backdrop. When a true-crime writer arrives to dig up a cold case from 1984, the town’s secrets begin to surface faster than the rising tide.
Packing Your Summer Bookshelf
When choosing your summer suspense, look for atmospheric settings—islands, remote cabins, or coastal towns—that mirror your own vacation vibes. There’s nothing quite like reading about a stranded protagonist while you’re enjoying the isolation of a beach.
