Resolute Fangs by Catherine Lievens

During a fight, you can either run or stand your ground.

Meyer never expected to become a member of a pack of wolves. He’s a vampire, and wolves and vampires notoriously hate each other, yet here he is, peacefully living with the pack.
Well, mostly peacefully.
Ollis never took things too seriously until his pack became the target of the dragon clan. His family still sees him as an immature teenager, even though he outgrew that phase a while ago. When his alpha asks him to step up and help guide the pack, Ollis readily agrees. No matter how frightened he is, he’ll defend his home.
And he won’t do it alone.
The pack is still at a disadvantage, but they have something the dragons don’t.
Each other.
