A retired adventurer must dust off his sword and gather old comrades to face down the demon lord who kidnapped his son in this action-packed fantasy from the author of the A Thousand Li series.

Once among the greatest of adventurers, Tai Lun retired to the frontier to raise a family and never looked back. When his son follows in his footsteps and is captured by the newly ascended demon lord, Tai's past comes calling-and there are dues to be paid.

To save his son, Tai must cross the ruins of a fallen empire and come face-to-face with the consequences of his past mistakes. If he hopes to succeed, he'll need the very best. Luckily for him, "the best" are his old friends, former companions on his adventures-if he can convince them to give up their comfortable lives.

One final adventure awaits them, with stakes greater than ever before: the life of Tai's son.
