Warrior, Come Again — Erin O'Quinn

Each man must return -- whether he wants to or not.

Ireland and Britannia, 433 AD. Four warriors return to a place ten years burned into their past, along with a fifth wheel who seems to have no business at all running with the big dogs.

The secret lovers Gristle and Wynn leave the relative safety of Derry in northern Ireland to seek a very bad man near the Wall of Hadrian, where both of them once led separate lives. Tristus, a priest-in-training, leaves the monastery of then-Bishop Patrick to help a brother who does not want his help. The high king's wise man Dub joins them all, traveling to the land where he sired his only son and left in sorrow.

And the fifth man? His name is Xan and he's infatuated with the would-be monk. Nothing, even fear and deceit, can stop him from following the trail of a desirable man…

This novel is the last of Erin O'Quinn's “Iron Warrior” trilogy.
