Dark Promise (Promises #1)

Joelle Quinn doesn't live much differently than any other working person, holding down two jobs and struggling to keep her head above water. But all of that changes when a vampire walks into her life. He doesn't ask for much: he merely wants Joelle to give her blood to another vampire, one who is nearly insane.

Talon struggles to hold the darkness at bay, fighting back a raging beast inside. The urge to kill and bathe in the blood of anyone in his vicinity is something he lives with every day—until he meets the one woman who holds the key to his sanity, and perhaps his very survival.
