Heavenly Desire — J.L. Sheppard

Jade Ashley has a past she'd like to forget and a destiny she isn't aware of. A stranger, Clyde, saves her from an attack and demonstrates extraordinary abilities she believed only she possessed. She soon realizes he's her guardian angel sent to reunite her with her long lost sisters, who like her are part of a new breed of immortals, Elementals, prophesied to determine the outcome of the upcoming war.

Clyde, an angel, battles the one thing he believes will lead to his fall from heaven--his new found emotions, forbidden among his kind. Nonetheless, the Angel Lords promise to promote him to warrior when he completes his last assignment--to find Jade. When he does, emotions he never knew possible arise. For the first time in two thousand years, he curses his existence, knowing she can never be his. Will he sacrifice his wings for a woman he loves but can't keep?
