Red Moon by Benjamin Percy
What happens when a plague like condition infects people through the bite of another infected person who has the lobos virus? They are called lycans, a type of wolf-like, incredibly strong and aggressive person capable of changing back and forth between lycan and normal human behavior. What if the government treats these people not as humans but as animals?
All out war, and a race of only a few to find a vaccine.
A very fun read for fantasy fiction lovers!
