Paradise Red — K.M. Grant

Master storyteller K. M. Grant brings the dramatic saga of young love and religious conflict to a satisfying end in the final book of the Perfect Fire trilogy. As winter falls upon the Occitan, Raimon must find a way to recover the Blue Flame from the hands of the evil White Wolf. But his plan could lead him back to the pyre -- and he might not be so lucky to escape from it again.
Meanwhile, Yolanda -- unwillingly married to Sir Hugh des Arcis -- is threatened by her husband's desire for a son. As Sir Hugh sets off on a mission to claim the Occitain for France, she makes her own journey through the blizzard to find Raimon, a journey that could end in disaster. As the flames rise one last time, Raimon and Yolanda's fates, like the fates of the Flame and the Occitan itself, hang by a smoky thread.
