In the last days of Narnia, far up to the west beyond Lantern Waste and close beside the great waterfall, there lived an Ape.
He was so old that no one could remember when he had first come to live in these parts, and he was the cleverest, ugliest, most wrinkled Ape you can imagine.
Many Narnian years have passed since Eustace and Jill helped ensure the Royal line. But when they are jerked back violently into this strangest of lands they find the present King in danger and Narnia facing its darkest hour. With Eustace and Jill at his side, the King, the noble unicorn Jewel and a few remaining loyal subjects must stand fast against the powers of evil and darkness and fight the Last Battle to decide the future of this once glorious kingdom.
