"It was pure joy to read and edit What You Don't Know by Bianca Sloane. Alternating between the violence unfolding at the Gilbert's and investigative interviews with their friends and family, Sloane transports us into a terrifying, brutal home invasion while constructing a brilliant plot that reads like an episode of Dateline. I was mesmerized and petrified through every page. Masterful and gripping, this is a suspense novel that any thriller lover will devour." -Samantha M.
