Havemercy

Thanks to its elite Dragon Corps, the capital city of Volstov has all but won the hundred years' war with its neighboring enemy, the Ke-Han. The renegade airmen who fly the corps' mechanical, magic-fueled dragons are Volstov's greatest weapon. But now one of its more unruly members is at the center of the city's rumor mill, causing a distraction that may turn the tide of victory. With Volstov immersed in a scandal that may have international repercussions, the Ke-Han devise an ingenious plan of attack. 

Led to victory by its magic-fueled Dragon Corps, Volstov has sent a delegation to its conquered neighbors to work out the long-awaited terms of peace. Among those in the party are the decorated war hero General Alcibiades and the formerly exiled magician Caius Greylace. But even this mismatched pair can't help but notice that their defeated enemies aren't being very cooperative. The hidden truth is that the new emperor is harboring a treacherous secret - and once it is revealed, Alcibiades and Caius may be powerless to stop it. 

During the war between the kingdoms of Volstov and Ke-Han, no fighter could match Rook for sheer arrogance and skill. Only Rook could ride the great dragon Havemercy, whose savagery and bloodlust matched his own. His brother, Thom, is bookish, diffident, and reserved, yet he yearns for Rook's approval - and fears he can never earn it. With the war over, and an uneasy truce between the two nations, Thom hopes the long-lost brothers can bond on a trip together. 

In the land of Volstov, Owen Adamo, the hard-as-nails ex-Chief Sergeant of the Dragon Corps, learns that Volstov's ruler, the Esar, is secretly pursuing plans to resurrect magically powered sentient robot dragons - even at the risk of igniting another war. Though Adamo is not without friends - the magician Royston and former corpsman Balfour - there is only so much he and his allies can do.
