Twelve-year-old Trina Bell has finally had enough. Why should she spend another dull summer watching Great-Aunt Roswinda lawn bowl and nibble cucumber sandwiches while her estranged father has all the fun? This year, she won't let him get away with his usual excuses. To her surprise, she succeeds. Her dad, the famous wildlife photographer, agrees to take her with him to the Canadian rainforest. Trina's triumph is short-lived, however; soon she finds herself alone on Vancouver Island, in a strange apartment building that may not be what it seems. But when she befriends Moss, the three-legged dog living across the street, and becomes involved in a puzzling case of vanishing hummingbirds, events take an astonishing turn. Will Trina be able to solve the mystery, and win the love of the father she longs for?
