Sensuous Gristle, badass former Roman soldier, has finally found love in the person of young Wynn, a pony trainer nearly half his age. Each man has a secret. For Wynn, it is the chilling sexual assault that he has suffered by two evil druids. For Gristle, it is the dread that any love he admits to will be wrested away by cold Fortuna, goddess of fate.

While the two men are trying to solve their inner turmoil, Gristle finds that his old friends in Wales are being threatened by invasion from ruthless Saxons. Even after they manage to handle the Saxon threat, new trouble waits on the sacred Hill of Tara, where the chief druids to the high king wait to strike again at the heart of Wynn.

Into this maelstrom of danger walks Dub, a striking warrior-scholar whom Gristle recognizes as a potent rival for the attentions of his handsome lover.
