Cowboy Blues by Delores Fossen

He promised he'd stay away…but he can't resist keeping her close

Setting rules and following them to the letter is part of cowboy Nick Haskins's code. It keeps life uncomplicated, and his heart intact. The love he had for his high school sweetheart is ashes in the wind, but he's not counting on her twin, Lindsay Gavin, to show up on his ranch – or in his dreams.

Lindsay's got a code of her own: hands off her sister's guy. But now that Nick is free to share his bunkhouse and his bed, she can't help but take what he's offering. There's no harm in satisfying years worth of curiosity. There's no shame in indulging in the sexiest fun of her life. Only, when Nick and Lindsay let desire set fire to the rules, will they both end up getting burned?
