Forbidden Single Dad: An Enemies to Lovers Surprise Pregnancy Romance by Laila King

My ex's brother hates me... But this gorgeous single dad doesn't know I'm pregnant with his baby. I thought I was house-sitting for a stranger. Turns out the penthouse belongs to Adrian Shaw—my ex’s grumpy brother. Yeah that Adrian. The man who’s hated me for years. The man raising his son alone. He wants me gone. But when his little boy collapses, I’m the one who saves him. Now I’m stuck here, playing house with the man I should never want. Watching him with his son wrecks me—he's tender, protective, broken in ways he won’t admit. But when his walls finally crack, one night changes everything. And I can't undo it—not even if I wanted to. But if my ex finds out I’m sleeping with his brother, he’ll destroy us both. Which would be easier to handle … if I wasn’t pregnant with his baby.
