Millie Marsh is a fiercely independent CIA agent. Mason Davis is a headstrong Navy SEAL. Join them for this second chapter of their story.

When Millie takes the final step toward the answers she craves, will she be forced to choose between her head and her heart?

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.

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?

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. Will this decision risk her relationship with Mason? Is she putting any chance she has of a happily-ever-after ending on hold to chase a ghost?

The Only Reason is a spicy and suspenseful Navy SEAL romance.
