Aspen in Moonlight by Kelly Wacker

When art historian Melissa Warren inherits three of her grandmother's paintings that have captivated her since childhood, she sets out to discover more about the little known artist and the locations of the mysterious landscapes. Her search takes her to the Colorado Bear Conservancy and the artist's great-granddaughter, Sula Johansen.Sula is reluctant to help Melissa, but their instant chemistry is impossible to ignore. Sula is torn between falling in love and hiding the truth about who and what she really is. Of course, if Melissa paid closer attention to minor details--like the fact that Sula enjoys nibbling berries off the vine, is unusually strong, and consumes way too much honey--Melissa might not be in for the shock of her life.
