Free-spirited black sheep, Taz Boran, has worked tirelessly as a nurse bringing efficient medical care to Africa for the past eight years. But when her sister Nicky is told she doesn't have long to live, she immediately flies home to small-town Eminence, Missouri.

Unfortunately, taking care of Nicky means being around her husband, Rafe; the one man Taz could never forget. Rafe is not only her brother-in-law but also took over the family veterinary clinic from her dad.

As Taz becomes Nicky's home health care nurse—working closely with Rafe to make her sister comfortable—their latent attraction comes sizzling back to the surface. They won't betray Nicky, but if her dying wish is to see them get the happy ending they always deserved, can they really keep fighting what's meant to be?
