Joanna Schaffhausen recommends

Blood on the Vine (2025)
J T Falco
"J. T. Falco's got all the goods here: a sun-drenched setting, believably kooky characters, a truly scary villain, and tough-minded but vulnerable Agent Lana Burrell trying to keep them all in line. Blood on the Vine is a chilling novel with as much heart and humor as horror, full of dark secrets and twisty turns guaranteed to keep readers awake deep into the night."

The Secret Next Door (2021)
Rebecca Taylor
"The Secret Next Door is a twisty tale of surprise and psychological suspense that is populated with relatable characters. Taylor has a zing to her writing style as the words fly across the pages...and every last one will have you wondering how well you really know your neighbors."

She Lies Close (2020)
Sharon Doering
"She Lies Close is an emotionally charged domestic thriller, packed with chills, and an unexpected ending that readers won't see coming. Sharon Doering's fast-paced, tension-filled debut makes her a writer to watch."
