July is bursting at the seams with so many new releases that wrangling this list was a challenge. I aimed to round up a wide range of new mystery and thriller releases that include middle grade to adult, a ton of fun tropes, a variety of mystery cases, and types of investigators—from amateur to forensic scientist!

First, some publishing date musical chairs: I listed Rachel Howzell Halls’ Fog and Fury in May’s releases, but it got moved to a July release so now you can officially go get it. Also out this month are time travelers solving cold cases, a murder mystery set in Martha’s Vineyard, a YA remote thriller, deadly games, a time loop murder mystery, a journalist in a cat-and-mouse game, and so much more!

But soon she’s wrapped up in solving a boy’s drowning that doesn’t make much sense…

Bonus: fans of sprayed edges will want to pick up the hardcover!

Ali Dawson works on cold cases with her team of investigators, but they are hiding a secret: they actually have the ability to collect evidence by traveling back in time! Now Ali’s in London during the 1850s with a murder case, but her son in the present time needs her on his own case…
