There's plenty about the grownup world that six-year-old Aoife doesn't understand. Like what happened to her big brother, Theo, and why her mama is in the hospital instead of home where she belongs. Uncle Donny says she just needs to be patient, but Aoife is sure her mama won't be able to come home until Aoife learns what really happened to her brother. The trouble is no one wants to talk about Theo because he was murdered. But by whom? With her imaginary friend, Teddy, by her side and the detecting skills of her nosy next-door neighbor, Aoife sets out to uncover the truth about her family. But she will learn that some secrets can't stay hidden forever, and sometimes the pain we bury is the biggest secret of them all.
