Night Quest (Nightsiders)

BLOOD ENEMIES, BOUND LOVERS 

He'd loved a vampire once, only to have her murdered by vengeful Freebloods. Now to save his son, Garret Fox must look to another Freeblood for help. Garret knows the empathic vampire Artemis can't deny his request once she reluctantly drinks his human blood. But although their connection runs deep, their attraction hot, Garret can never forget what Artemis truly is. 

Sharing Garret's thoughts and feelings has wreaked havoc on Artemis's emotions. But when she discovers a malevolent force bent on destroying them, she finds herself drawn even closer to the human. Dare she ever hope to find a home with a man who hates her very kind if they can first survive the evil allied against them?
