Kingdom of Summer is the second book in a trilogy of fantasy novels written by Gillian Bradshaw.

As a favor to his father, Gwalchmai takes him to Camlann, King Arthur's stronghold, where he can find himself a master.

Rhys finds the fortress a pleasant place; all there are caught up, to varying degrees, with Arthur's vision of uniting and bringing peace to the land.

Publishers Weekly states that "Bradshaw's second Arthurian tale ... surpasses 2010's Hawk of May in bringing the world of a Roman Arthur to life.

... Arthurian retellings rarely come from the voice of a freeman, and Rhys's grounded perspective enhances the fantastical elements.

Adults and young readers alike will be delighted by Bradshaw's engaging mix of history, legend, and romance.
