Trista is a Celtic warrior girl and seeress. Her visions are always horrifying, full of blood and death. And one of her premonitions tells her she must escape from the tribe who have captured and enslaved her, for their time is running out. Fleeing into the snowy forest, she runs straight into two Roman soldiers and thinks this time the game is surely up. Surely she cannot survive a second time? But one of the soldiers has a secret - he is a shapeshifter. Part wolf, part man, Morcant also has both Roman Celtic blood in his veins and he has never felt truly at home in either world.
