A Window in Time by Carolyn Lampman from Books In Motion.com

One beautiful, breezy day Brianna Daniel's hot air balloon joyride turns into "gone with the wind", as she is somehow blown back to the year 1860. Bumping along the road to the Split Rock pony express station as a mail-order bride to Lucas Daniels, Brianna realizes that she has exchanged lives with her great-grandmother Anna. The thoroughly modern Brianna is hardly the docile bride that Lucas, her groom-to-be, had in mind. In fact, they dislike each other instantly. But beneath that fiery conflict sizzles something even more intense and impossible to ignore. As this century meets the last, two unlikely lovers unite in a flame of desire that will endure through the ages.
