King Breaker by Rowena Cory Daniells
The story of Byren, Fyn and Piro picks up immediately where the cliff-hanging ending of The Usurper let off!
When Cobalt stole the Rolencian throne, Byren, Fyn and Piro were lucky to escape with their lives; now they've rallied, and will set out to avenge their parents' murders.
Byren is driven to defeat Cobalt and reclaim the crown, but at what cost? Fyn has sworn to serve Byren's interests but his loyalty is tested when he realises he loves Byren's betrothed. And Piro never wanted to win a throne, but now she holds the fate of a people in her hands.
