Curse Breaker by Heather Walker

The final installment of the Phoenix Throne series sees Christie McLean leave his home on the Isle of Mull to seek help from the dragon shifters of Urlu. But the trip doesn’t go as planned. He meets up with Alexis Morgan, the mysterious woman who cast the curse on his family. They spend a single night of drunken indulgence at a roadside inn, and things start spinning out of control for both of them. Before they know it, they find themselves embroiled in a shadow world of power and mystery where nothing is as it seems.
Will they both succumb to forces beyond their reckoning before they can find the key to the puzzle?
Finding the power to fight the curse is only half the battle. The hardest part will be overcoming their reserve to find each other in the darkness and lead each other back to the light.
