Twins Under the Tree by Leigh Riker

He never stayed put...until she gave him a reason to.

Rebel cowboy Hadley Smith had never been one to stick around. Then he suddenly became a single father - to twins. Hadley doesn't need Jenna Moran looking over his shoulder, but he grudgingly starts to fall for her compassion and strength. When faced with an impossible choice, can Hadley prove to Jenna he's willing to put down roots?
