Sara Summers is the standout teacher at West Lebanon Middle School—admired, envied, and quietly resented. The attention she receives is constant—often flattering, but sometimes unsettling. So when anonymous emails from a 'secret admirer' land in her inbox, she barely reacts. But everything changes when a package arrives on her doorstep containing an explicit object and a threatening note. Terrified, Sara contacts the police, but they offer little help.

Desperate for protection, Sara turns to Justin Boyle and the International Investigators. Their search uncovers a tangle of obsession and deceit, and every person in Sara's orbit becomes a potential threat. The principal has a history of crossing lines. The gym teacher can't keep his eyes—or hands—to himself. A jealous frenemy seems eager to watch Sara fall. An abusive ex refuses to let go. And a troubled student lingers long after the final bell. Any one of them could be the stalker closing in.

What begins as a simple secret admirer case spirals into a deadly game of cat and mouse. Someone is hunting Sara, and they won't stop until they get exactly what they want.
