Scout by Macy Blake

Coal Volsunga is a dragon convinced he’s better off alone…
As alone as a dragon who is part of a pack can be, that is. Although he loves the work, his feelings are starting to get involved, especially for a wolf entirely too involved with pack life for a loner like Coal.
Jack “Scout” Jerrick is a wolf with two packs, but only one heart…
Dividing his time between his father’s pack and his new one hasn’t been an issue for Scout. He’s learning to protect the secrets of the shifter world and the innocents involved in a dangerous war over magic and power. But when he develops feelings for the cantankerous dragon in his new pack, things begin to get a whole lot more complicated.
After Scout is kidnapped by the mysterious threat hunting their pack, Coal realizes being alone isn’t his life’s mission after all. If he and Scout are able to survive, they must
…put aside their preconceived notions and work together to save their pack,
…learn to love and heal when nothing is as it seems,
…and realize when it comes to being mates, there’s nothing they won’t do to save each other.
