When eight-year-old Tessa Lee and her brother, Travis, are abandoned in a campground by their desperate mother and her boyfriend of the moment, they are left with only two things: a phone number written in Magic Marker on Travis's back and their mother's favorite housecoat, which she leaves wrapped around her sleeping children. This housecoat, painted with tiny fireflies, becomes totemic for Tessa Lee, providing a connection to her past and to the beautiful mother she lost.

Seven years later, when word arrives that her mother has been spotted working at a tourist trap on a seaside boardwalk not far from where Tessa Lee lives, she sets off on a dangerous journey to try to recover what has been taken from her.

Steeped in the rich Southern atmosphere for which Sheri Reynolds has long been hailed, Firefly Cloak is a vivid coming-of-age novel of family, loss, and redemption.
