Of Knights and Books and Falling in Love by Rita A. Rubin

This comes with an unattached signed book plate

Jayce has little memory of life before entering servitude to the Dark Lord, and no hope of ever escaping. Until he meets Alexius, the knight with a heart of gold. He offers Jayce, his enemy, a chance to break free of the Dark Lord's clutches, and Jayce is not about to let such an opportunity pass.
When the war comes to an end, Jayce finds himself finally free, with Alexius's help, and surrounded by a new world of opportunity. And the prospect of a new love. The more time Jayce spends with Alexius, the more he finds himself falling for this knight in shining armour.
