Annie Its a stand alone series...but I still recommend Virgin River....its a wonderful cant put down series....and you will love it!!!
Heather M They refer to a character in Virgin River, but it's so minor that you definitely don't need to read that series first. :)
Lajuna If you ever want to read the Virgin Valley series there is Grace Valley (3 books) before that. They are as easily connected as Virgin Valley and Thunder Point.
