First Comes Love - Penny Siobhan

With her thirtieth birthday looming, no romantic prospects, and a dream of motherhood slipping away, she's down to one last, desperate option: a decade-old pact made with her estranged childhood friend, Silas Beckett.

There's just one hitch: Silas is now a superstar baseball player with a Playboy reputation, and their friendship is a distant memory.

Still, he agrees to their clinical, business-like plan: have a baby through fertility treatments, co-parent as best friends, and keep their hearts strictly out of the equation.

But through sterile waiting rooms and late-night hormone shots, the old intimacy that once defined them rekindles into something deeper and far more dangerous. As the line between platonic and passionate blurs, their carefully constructed plan begins to fail in more ways than one.

When they're left with nothing but failed treatments and inconvenient feelings, they have to face the fact that what they really want might not be a baby, but each other.
