Young Rosie can understand animals’ emotions and fragmented messages, yet she often misinterprets them. After she is placed in foster care with the Vale family, she is rejected by her older brother Ethan and suspected by their father Alexander. Scattered clues left by an old dog, a crow and a fox guide the siblings to seek verifiable human evidence, gradually uncovering the truth behind their mother Claire’s death in the fire. The investigation draws the fractured father and son, as well as the unfamiliar brother and sister, together into a family. It also reveals that Rosie was not abandoned — she had once been protected by Claire.
