Zoe Prescott has always wanted to be a mother-but a looming medical condition has placed a cruel deadline on her dreams. With time running out, she knows she needs a partner who's willing to help her become a mom before it's too late. She never expected that person to be her boss. Matthew Dalton is grieving the loss of his last remaining family member. When Zoe confides in him about her ticking clock, he offers a solution: they'll get married in secret and try for a baby together. No strings. No expectations. Just a practical arrangement between two adults.

But as their secret marriage deepens into something more, their hearts get tangled in the most unexpected ways. And when it seems the dream of a baby might not come true after all, they discover that love-real, lasting love-was the true miracle they never saw coming.
