Lullaby (Ellie Jordan, Ghost Trapper Book 7)

Life is more difficult than ever at Savannah's only ghost-hunting detective agency. While Ellie copes with her mentor's departure and other unwelcome developments, she also worries about the supernatural injuries keeping her boyfriend caught in an endless slumber. At the same time, Ellie and Stacey are called in to investigate an eerie entity haunting a baby's nursery room. The ghost appears late at night, its face barely visible on the baby monitor, and sings a chilling song. Soon, Ellie learns there are more ghosts in the house, and at least one of them is a dangerous, child-hunting monster who must be stopped before it kills again.
