A scrappy dog named Bob and his best friends, Ivan the gorilla and Ruby the elephant, undertake a dangerous journey to seek Bob's long-lost sister, but a storm is approaching and time is running out.

"Bob is an independent dog. He knows he could still make it on his own if he had to, even though he now has a home with his human friend Julia, regular meals, belly rubs, and a bed to call his own. But most important of all, he still gets to visit his best friends at their new home. Ivan, a silverback gorilla, and Ruby, a young elephant, live nearby in a sanctuary. A home for Bob, a home for his friends, and all the treats he could want -- but something's missing. Someone is missing. Someone who Bob thought was gone, forever. Until the day he realizes she's not. A lot can go wrong in the moment left to chance, the blink of an eye, the bounce of a bone. When a hurricane hits, Bob sets out on a dangerous journey in search of his long-lost sister, with the aid of Ivan and Ruby."--

In this novel-in-verse that picks up a few months after the events of The One and Only Bob, Ruby recounts her life before the circus when her caretaker from the elephant orphanage in Africa comes for a visit.
