Dorothy Keddington is one of my all time favorite authors. These are her first two books and they are great. They are romance adventures that will keep you up late into the night wanting to find out what happens next.
Jayhawk is 1/2 Bannock-Shoshoni Indian who wants to find out why his father disappeared a few weeks before he was born. Angela Stewart arrives to visit her college roommate at her family's ranch outside the city of Dust, Wyoming. Together Angela and Jayhawk go on a wild ride to find out the truth.
Return to Red Castle is set in the High Uintas. Melissa is returning to her family's vacation spot for the first time in four years where she finds her best friend (though 11 years older than her) has become a mountain man and where drug runners are in the mountains.
NOTE: Both books are out of print but can be found at half.com.
