Waking Bel by Jocelynn Drake

Beltran Varik believes in science.
It holds all the answers he seeks.
Except for one.

How in the world did he end up falling in love with two werewolves?
Of course, there was no way science could account for the beauty, warmth, and mind-blowing sexiness of Wyatt and River.
The two shifters are outcasts from their own kind and must seek the protection of a vampire.
Bel might take them in out of a need to keep them safe, but his feelings for them grow into something so much deeper.
Unfortunately, Bel might have to choose between his wolves and his family as a fight brews with the local werewolf pack and the Variks face a darker threat from the Ministry.
