From beloved author Katherine Applegate comes The One and Only Family, the final instalment in the series that began with the Newbery Medal-winning, #1 New York Times bestselling modern classic The One and Only Ivan and its sequels, The One and Only Bob and The One and Only Ruby. 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 Katherine Applegate has crafted a poignant, delightful, heartbreaking, unforgettable final foray into the world of Ivan, the world's favorite silverback.
