Thai Twist by D. R. Ransdell
For high school graduate Gina Campanello, winning a trip for two to Thailand seems more like a chore than a prize. The only available travel companion is her sister, the country is a long plane ride from Tucson, and besides, she’d rather stay in town and flirt with college boys. But when a neighbor asks Gina to deliver a package, she has a mission. While Rachel visits every available temple, Gina checks out leads. She has so many setbacks that by the time she learns that the man she’s looking for lives in Chiang Mai, she’s en route to Phuket!
