Callahan Cowboys are bachelors for life! That is, until Pete Callahan's wily aunt delivers her ultimatum. The first Callahan to marry and have children—the more kids the better—wins the family ranch. Like his five brothers, Pete never considered himself the marrying kind. And that's just fine with Jackie Samuels, a hardworking nurse who seems perfectly happy with her and Pete's Saturday-night arrangement. Until she realizes she wants something more from the hunky, footloose rancher. Like a father for the triplets she just found out she's having. Pete couldn't be more delighted. He's suddenly got an instant family. Jackie's the only obstacle to their happy ending—she refuses to marry him. But maybe she knows the best way to land a cowboy is playing hard to get!
