The Only Reason by Donna Schwartze

I love Millie and Mason so much. I wish you would write about them forever. They have such a sensual romance. And this one has a bit of a love triangle! The twist in this book is amazing.—Reader Review
Reality. Who needs it? Definitely not Millie. She’s had enough to last a lifetime. In the past six months, she finally found out who killed her mom and took out a terrorist network in the process.
Phew! Enough reality. It’s time for a little fantasy. And she’s definitely got the right man for that: Navy SEAL Mason—the alpha male with a tender side—who protected her from danger and healed her broken heart. Then he made a life-changing sacrifice just to be near her. Who could ask for anything more?
But two months into living in this blissful bubble, reality strikes again. Millie’s boss tells her a shocking secret. It’s news Millie has been wanting to hear for almost nine years. But is it the truth? Or is her boss only dangling this tantalizing tidbit to get her to take on another dangerous mission?
There’s only one way to find out—dive headfirst back into reality. But will this decision risk her relationship with Mason? Will she lose the small amount of peace she’s been able to find? Is she putting any chance she has of a happily-ever-after ending on hold to chase a ghost?
