Corsair 

Corsair by Tim Severin is the first swashbuckling adventure in the Pirate series. 1677. On a late-summer’s evening, two ships lurk off the coast of southwest Ireland. Seventeen-year-old Hector Lynch wakes to the sound of a pistol shot as the Barbary corsairs raid his village, and he and his sister are snatched. Separated from each other, Hector is sold at auction in Algiers, and thrown into a bewildering world where life is cheap and only the quick-witted survive.In North Africa, Hector befriends fellow captive Dan, a Miskito Indian from the Caribbean, and the two men convert to Islam to escape the horrors of the slave barracks — only to become victims of the deadly warfare of the Mediterranean. Serving aboard a Turkish ship, their vessel is sunk at sea and by a savage twist of fortune they are chained to the oar bench of a French galley.Desperate to find his sister, Hector finally stumbles on the chilling truth of her fate when he and Dan are shipwrecked on the coast of Morocco.
