When exhausted new mother Frida attends Baby Rhyme Time at the local library, she feels a sense of purpose that has been lacking in her anxious, apartment-bound, sleep-deprived life. But at the end of the session a piercing scream is heard, followed by the thump of a body, and the library becomes a crime scene.
Before long, Frida finds herself part of an unlikely group of sleuths investigating the murder. Between gossip and cups of magic at their local cafe, they are too busy having fun to realise how close they are to danger . . .
