Guardians of the Mountain by Curtiss Robinson

Imprisoned…deceived…betrayed… “My love, Theila is held captive…my own kinsmen have failed me and my mind…well, I am not myself.” 
Wavren, Da’Shar, and Rosabela have been tasked with destroying the very essence of lycanthrope but the sacrifice is great. Which is greater; the life of an innocent man or the soul of a hero? One will be taken.
