By Jean Marie Brown Jodi Thomas’ latest offering in her “Whispering Mountain” series, Promise Me Texas, set in 1879, is best described as a romantic comedy. Beth McMurray is the youngest daughter of Jessie and Teagan, the eldest brother in the McMurray clan. Beth, or Bethie, is a headstrong woman who’s described as “spoiled” and “temperamental.” But mostly she’s a lot of fun.
