I never should have agreed to marry my older brother's best friend, but I was in a bit of a jam.

Aston Hughes is gorgeous, arrogant, and irritatingly broody. The single dad is also the new trauma surgeon at my hospital and my temporary roommate.

Two years ago, we shared a mistaken kiss during a blackout, and nothing's been right between us since.

So really, I shouldn't have said yes when he suggested a marriage of convenience.

But after leaving my bad ex behind, I discover I'm pregnant with his baby, and I'm scared.

Aston offers to marry me as protection from my ex in exchange for helping out with his daughter, who needs more stability in her life after recently losing her mother. It's an unfortunate no-brainer.

Only what starts as a simple business arrangement quickly turns messy. Heated. And soon he's no longer fighting with me but for me as he calls me his wife and claims my baby as his.

Except nothing is that simple or easy for any of us.

Now here I am, falling for the hotshot doctor and his daughter while our lives come undone around us.
