Wicked Angels by Michele Hauf

Sequel to Dark Rapture

"In the stunning sequel to Dark Rapture, Vince Lyons asks for Scarlet's help in translating some old diaries, hoping they'll reveal his past. Scarlet agrees, but for her own reasons. Vince was "in-born" to vampirism and she hopes to uncover truths about the lifestyle she shares with her one true love, Sebastian. After all, there must be more than simply needing blood, mustn't there?" (from Amazon.com)
