Thin Ice by Mary Alford

They’d been flirting around the edges of romance for years. Now, with Legion coming after them full force, will saying I love you come too late for Abby and Brookes?
With the world on the verge of collapse, Abby Temple, and her partner, Brookes Zachary, must save the life of the most important man in the country if they ever stand a chance at ending Legion’s tyranny.
But rescuing the president is just the beginning. There’s a whole country filled with Legion’s troops standing between them and the safety of Strike Force headquarters. And the odds of having the future with Abby that Brookes dreams of is about as likely as surviving their last mission.
