Jasper Drake (Aurum Court Dragons Book 5) by Emilia Hartley

This is finally about the king of dragons. Here we see Jasper finally step up as king and take the responsibility he should have taken when his father died. Although his mate, Cora has brought a war to his doorstep, his dragon finally starts to meld in with the man. I've liked this series, but with this story; it has finally all come together.
