Knight and the Necromancer - Book 2: The Border - The Knight and the Necromancer, #2

Roland thought necromancers were inhuman monsters. Until he met Sairis. Roland and Sairis have escaped from a traumatic assassination attempt, solved the mystery of their attacker, and enjoyed plenty of heavy petting along the way. Roland knows that it's too soon for love, but he feels like he's falling head over heels. However, in the final moments when their attacker is revealed, Sairis does something unthinkable.
He transfers a brutal spell to Roland, nearly killing him, and disappears. Roland is left reeling, struggling to cope with his injuries, and wondering whether everything Sairis said and did was a lie. Did Sairis seduce Roland only to use him as a hostage? And if not, what has happened to Sairis?
