How to Marry a Cowboy/Reckless in Texas by Carolyn Brown and Kari Lynn Dell.
Spoiler:
How to Marry a Cowboy: Texas rancher Mason Harper’s daughters want a new mama in the worst way, and when a beautiful woman in a tattered wedding gown appears on their doorstep, the two little girls adopt her-no ifs, ands, or buts about it. Mason isn’t sure about taking in a complete stranger, but Lord knows he needs a nanny, and Annie Rose Boudreau stirs his heart in long-forgotten ways…
Reckless in Texas: Violet Jacobs is fearless. At least, that’s what the cowboys she snatches from under the hooves of bucking horses think. Outside the ring, she’s got plenty of worries rattling her bones: her young son, her mess of a love life, and lately, her family’s struggling rodeo. When she takes business into her own hands and hires on a hotshot bullfighter, she expects to start a ruckus. She never expected Joe Cassidy.
