Gideon's Heart by Faith V. Smith
Every night detective Gideon Hawks walks a dangerous beat through the streets of Savannah, but when he meets Katheryne Alastair, he discovers a new threat...this one to his heart. Her delicate, sensual features and old-fashioned clothing lead him to believe she is homeless. Against his better judgment, he takes her home. Katheryne, a vampire ready to end her existence, lies in wait for the approaching sunrise. But when the handsome detective attempts to help her, she finally finds peace within her heart. The heat of his touch triggers a blood lust she's kept dormant for centuries. Is it possible Gideon is her soul mate? When Gideon is mortally wounded, Katheryne cannot let him die. If she turns him, will he forgive her, or worse, walk away? Or will the eternal love she holds for him end the suffering of her centuries-old vampiric curse?
