Losing a sibling is hard. Losing three of them is even harder. Repairing a broken bond of trust is harder still. After his three brothers disappeared, one after another, gone to a mysterious place known only as The Rainbow Bridge, Buddy the degu is all alone in his cage. Confused and frightened, he knows only one thing for certain: he last saw his brothers in the hands of the human caretaker. That knowledge breaks the bond of trust forged between Buddy and his human in the years since he was a pup, and leaves him convinced that letting her get her hands on him will mean he disappears too. Somehow, she has to convince him he's wrong, and earn back his trust.
Based on actual events that took place in the life of one of the author's own degus, and told from the point of view of a degu, this is the story of how patience and love taught a confused and terrified rodent how to trust again.
