Countdown, book 1
Matteo and Gabe have everything they could ever want out of life, except a family of their own. When Gabe's bossy, but well-meaning, twin sister offers to be their surrogate, the stars seem to have finally aligned for them. But with his sister running the show, the new dads-to-be begin to wonder if they're going to survive the nine-month countdown.
Originally published in 2012 - this is a total rewrite with a pretty, new cover.
