Treylen and his dragon, Rime, have left the assassin's life behind them. Now, ambassadors to far-off lands, they're ready to settle down and take it easy.
Old habits die hard, though. Treylen makes a dangerous promise—to teach the king's daughter to bond with a dragon of her own. To do it right, she must put aside her royal ego and survive the deadly training. And the whole city is watching their every move. If Treylen succeeds, he will have a powerful ally in the war. If he fails, the alliance is broken.
When things go awry, Rime and the princess gamble on a plan of their own, launching a quest to the hellcaves, where horrors lurk and lost secrets await.
For the others, this is the journey of a lifetime. For Treylen, it's just nice to be out of the public eye. But, nothing ever goes to plan. When old friends come knocking and enemies show up in the most unexpected places a hidden plot will unfold, and a race against time will begin.
Which bonds will be broken? Which will be reforged? And what dark histories will be uncovered in the bowels of pentearth?
