I'm in It (Reed Brothers Series #10)

Mick fell in love with Wren at the worst possible time. She was in the midst of something wonderful, and then she wasn't. Her life changed in the blink of an eye. In this situation, it wasn't a change for the better. He can still remember when she felt the first cramp, when she pressed her knees together tightly in the front seat of his car as though she could hold that life inside herself by sheer will alone. If will were all it took, she'd have succeeded.

But she didn't succeed, and they were over before they began. She was too hurt. She was too raw. She was wishing for what could have been, while he was wishing for what was. And what was... well, it was nothing. At least not to her.
