She's hiding a secret from this rancher that may change everything...  Georgie Romero's daddy had one die-hard rule: do not get involved with Austin Calloway. Yet when she left town six years ago, her fling with the blue-eyed heartbreaker wasn't the only secret she hid. Now the job of a lifetime has brought her--and her young son--back to the Calloways' Texas ranch...and the sizzling chemistry with Austin that still lingers.  As the daughter of a rival family, Georgie has always been forbidden. But Austin's never been one to follow the rules. Will he feel the same way about Georgie once he learns about their son?  An Heir for the Texan is part of the Texas Extreme series.
