In the Lord of the Isles, Drake returns to fantasy with an adventure set in an extraordinary world where the elemental forces that empower magic are rising to a thousand-year peak. Into this world, survivors from the last magical peak intrude: Tenoctris, a quiet and scholarly sorceress swept out of the past at the moment of final catastrophe as her civilization sank beneath the sea; the ghost of the greatest ruler, King Carus of the Isles; and the great magician known only as The Hooded One, who actually caused that ancient catastrophe.

In the days following an unusually severe storm in a tiny seaport town, life is disrupted. First, young Garric rescues the castaway Tenoctris; then, amazingly, a huge galley lands, bearing a court envoy searching for the lost heir to a dukedom - and finding her in Sharina, Garric's sister. Immediately after the galley departs with Sharina to seek out her destiny, another party arrives by coach, led by a merchant sorcerer eager to hire Garric. He sets out with this party, accompanied by Tenoctris and by the shepherd Cashel and his sister, Ilna, both of whom are discovered to have some magical power. Garric and Sharina, Cashel and Ilna, all travel toward romance, danger, and astonishing magic that will transform them and their world.
