After being burned in the past, brooding Winthrop Christopher was now twice shy, to say the least. So when Nicole traveled to Winthrop's Montana home, she was prepared for a standoffish host...and instead found the most intriguing man she'd ever met.

After his ex-fiancee left him high and dry, Winthrop refused to give any woman the time of day. Despite his determination to keep young Nicki at bay, however, this Montana man unexpectedly found himself desiring love again. Could Winthrop learn to put aside his deep-seated mistrust and learn to love the innocent beauty who stole his heart?
