He has a medical file that says he can't be a father. I have a positive test that says he is. Now, my billionaire best friend thinks I'm the ultimate liar.

We made a pact on a cocktail napkin ten years ago: If we're single by thirty, we marry each other.

It was supposed to be a joke. A safety net. But as the clock ticked down to my thirtieth birthday, the line between "best friend" and "only option" blurred. One stormy night, a red dress, and too much tequila turned our friendship into something hot, messy, and irreversible.

Then, the miracle happened. I'm pregnant.

I thought Bennett would be happy. I thought we beat the timeline. Instead, he looked at me with cold, gray eyes and kicked me out of his office.

His secret? Bennett Hines, the genius architect who designs skyscrapers, is medically sterile. He has the paperwork to prove it. He thinks I cheated. He thinks I'm trying to pin another man's baby on him to secure his fortune.

But when a dangerous ex comes after me, Bennett doesn't hesitate. He moves me into his fortress -- the Glass House on the cliff. He feeds me, protects me, and claims me in front of the world to save my reputation. He plays the doting fiancé perfectly for the cameras, but behind closed doors? We are strangers.

He's waiting for the truth to come out. I'm waiting for him to realize that love is the only math that matters.

But with a high-stakes merger on the line and a storm of the century rolling in, my time is running out. Can I convince the man of logic to believe in a miracle before I lose him forever?

The Birthday Proposal is a high-stakes, angsty, best-friends-to-lovers romance featuring a possessive billionaire architect, a "miracle" pregnancy, and a grovel that will bring you to your knees. No cheating (really!), plenty of steam, and a hard-earned Happily Ever After.
