And here's a slightly longer blurb!
As Rome conquers Cymru, Centurion Maximus falls under the spell of ethereal Druid princess, Carys. Charged by his Emperor to eliminate all cursed Druids before they rise up against their new masters, Maximus is unaware of her heritage and is determined to possess her and discover where she and her kin are hiding from the might of the Eagle.
Despite knowing he's the enemy of her people, Carys is fascinated by this commanding foreign invader, a barbarian who displays unexpected honor, and willingly meets him in secret to satisfy her desire for sexual pleasures. But when Maximus captures her heart her loyalties are twisted and freedom from Rome is no longer her single-minded obsession.
As the summer solstice approaches Aeron, the High Druid and ex-lover of Carys, gathers the dark gods to crush the enemy into oblivion, the Druids into submission and Carys to his will. Maximus and Carys must defeat the encroaching devastation, overcome the prejudice of their warring gods and opposing cultures and find a way for their love to survive.
Now I just have to write book two!!!
