Courting Cate, Courtships of Lancaster County Series by Leslie Gould and published by Bethany House Publishers.
When Amish farmer Pete Treger moves to Paradise Township, Pennsylvania, he meets Cate and Betsy Miller. Both are beautiful, but older sister Cate is known more for her sharp tongue and fiery temper than her striking appearance. Betsy, on the other hand, is sweet and flirty,and seems to have attracted most of the bachelors in Lancaster County!
However, the sisters' father has made one rule: elder sister must marry first, before the younger can even start courting. Though he finds both sisters attractive, something about Cate's feisty demeanor appeals to him. Soon the other bachelors in the district convince Pete to court Cate. She hardly seems receptive to his overtures, though. Instead, she's immediately suspicious of his interest.
