When a teen boy who excels at being unseen finds himself hiding in his ex-girlfriend’s house, he uncovers carefully concealed truths—about her, her family, and himself—in a twisty mystery with a shocking surprise. One night, a lovelorn teen boy “accidentally” slips into the home of his ex-girlfriend, Laura, and ends up hiding in her basement, trapped in the house by its alarm system. How long can he stay hidden? What will happen if he is found? What will he learn about Laura—and himself—in this house? And what is his true motive for being there? Turner’s affinity for observant outsiders—and teens who share a desire to hide from nosy adults and judgmental peers—shines in a psychological thriller in which the slow burn of tension keeps readers turning pages to a sudden twist that changes everything.
