This is the latest adventure in the series that has won the Newbery Award. Powerhouse author Katherine Applegate invites readers back into Ivan's world for one last adventure--his most exciting yet.

Ivan has been happily living in a wildlife sanctuary, with his friend Ruby next door in the elephant enclosure, frequent visits from his canine friend Bob, and his mate Kinyani by his side. And in the happiest turn of all, Ivan and Kinyani have welcomed a set of twins to their family!

Ivan loves being a papa, even though it can be hard sometimes. But as he navigates the joys and challenges of parenthood, he can't help but recall his life before the glass walls of the mall circus, his own childhood in the jungle--and his own twin.

In the tradition of timeless classics like Charlotte's Web and Stuart Little, The One and Only Family is a poignant, delightful, heartbreaking, unforgettable final foray into the world of Ivan, the world's favorite silverback.
