Fall is here, and for publishing, that means the release of blockbuster books and a heavy dose of horror, gothic, and moody fall reads. Louise Penny fans can now run to her 20th Inspector Armand Gamache, Black Wolf ; Freida McFadden fans can now grab the thriller The Intruder; and Reese Witherspoon teamed up with Harlan Coben to write Gone Before Goodbye. As your steward into October’s new releases for mystery, thriller, and true crime reads, I’ve aimed for a wide range of themes, tropes, crimes, and moods while also adding a few horror-October vibed treats.

This month’s selections have a bit of everything, from a campus-set suspense novel to strangers locked in a nightmare motel! There’s also an Edwardian era Gothic mansion, a family of spies in a secret world organization, true crime with a wrongly convicted man the state wouldn’t free even after the real killer confessed, and much more!

Win a shiny library cart for your home ! Let the good reads roll on its durable build and lockable wheels. Easily roll your current reads, favorite literary journals, or your entire TBR list from room to room.
