Ancient Warrior by Katie Reus

The last time she saw him…
Long before The Fall, before the world changed forever, tiger shifter Harlow worked in Black Ops for the safety of all shifters. She excelled at her job, loved everything about it, until the male she loved tried to kill her. So she was forced to kill him first.

She killed him.
Now Aodh is back. And this fierce, dominant dragon shifter won’t stop until he gets answers. But things aren’t what they seem and now he has more than a battle with Harlow on his hands. If they want a chance at a future, they’ll have to take down an ancient enemy who has targeted not only them, but their friends—and it’s going to take uniting all their skills to survive.

Author note: Each book in the series can be read as a stand-alone, complete with HEA and no cliffhanger
