from Blood and Magic - Wizard's Spawn, #1

...a surge of something escaped his hand and the bow of the pirate ship blew away. Wizard's Spawn, a new series from the author of the Warriors, Heroes, and Demons trilogy, follows the exploits of a new generation. Nails and Brayson are misfits by birth. Brayson-a Cross, son of a faerie and a human-should live in the comfort and safety of Crosstown, but the circumstances of his conception force him to flee.
Nails-a boy created from magic and the blood of his mother's, dead, KaAnian lover-is left with powers he does not understand and cannot control. Nails' and Brayson's friendship, and their need to belong somewhere other than on the outskirts of society, sends them on a quest to find a way to rid Nails of his magic. But, in a land full of slavery, pirates, faeries, wizards and thieves, every step contains danger and calamity until Nails must face the ultimate challenge; accept his magic or kill Brayson and all those he holds dear.
