Chick Lit at it's best. I loved Lisa Wingate's "Lone Star Cafe" so I had to give this one a try. I didn't like it quite as much but still liked it a lot.
Lindsey, the twin sister of Laura (main character of "Lone Star Cafe") Is set adrift when her daughter goes to Mexico for a summer visit with her father. Lindsey joins her sister in Texas on an undercover mission to find stolen dinosaur tracks. Laura has talked her into taking a horse-psychology classes as a cover. She saves a big white dog from being killed by a rancher. Then she meets Zach Truitt, the rancher/owner of the place. Through serious and funny situations, Lindsey and her daughter find home.
