Trust the Enemy by Catherine Lievens

The enemy of your enemy might just be your friend.

Charles is getting back on his feet. After losing almost his entire family in an attack on his clan, he’s found a new home in Mayport. He might be a dragon, but he finds that living with bears suits him just fine. He should be happy, and he would be.
If only he didn’t have to deal with the knowledge that the coven that attacked his clan is now planning to attack the pack.
Red is happy to have found a home after his time living on the streets. He wants to bring his grandfather to Mayport, but not until he’s sure the pack is safe.
Luckily, Chance is a good alpha, and when the opportunity presents itself to find allies within the coven, he takes it. The problem is that no one knows if they can trust these mages.

If they can’t, it will mean the end of the pack.
