Lone Star Twins by Cathy Gillen Thacker

Best friends...with benefits!

For two people who aren't in love, Poppy McCabe and Air Force Captain Trace Caulder have pretty amazing chemistry. And now the long-time buddies and sometime lovers are about to get their most passionate wish: becoming the adoptive parents of twin babies! The catch? They have to get married.

Suddenly, Trace wants to be there for Poppy 24/7. Except he's stationed overseas. So he only has a thirty-day leave to convince the woman who shares his complicated past that they can have it all: a family and forever!
