It's too hot out and most of Tumblr is already in "how long til October" mode, but Summer can be spooky season too!
Empty Smiles by Katherine Arden: middle grade horror, fourth in chilling and intensely atmospheric Small Spaces quartet.
The Lake House by Sarah Beth Durst: creepy and suspenseful YA wilderness survival story about three girls who arrive at an off-the-grid summer camp only to find no one left alive -- except whatever is hunting them.
The Devouring Wolf, by Natalie C. Parker: coming-of-age adventure featuring terrifying legends come to life, friends, foes, and queer werewolf kids.
The Honeys, by Ryan La Sala: sun-drenched summer horror set at the elite, bucolic Aspen Summer Conservancy Academy, where Mars knows he'll never fit in -- but which may explain his sister's death. Psychological suspense, toxic traditions, complex friendships, bees.
Bone Gap, by Laura Ruby: lyrical and haunting combination of science and myth, magic and realism, beauty and rage. In a town where people sometimes slip through the gaps, no one asks too many questions when Roza disappears. Nobody except Finn, who knows she was taken -- but who can't describe the man who took her. And there are more bees.
Camp Sylvania by Julie Murphy: body shaming isn't the only horror awaiting Maggie Hagen at summer "fat camp." Spooky, hilarious, heartfelt middle grade.
