Novus (The Cresecren Chronicles, Book 1) by Crystal Marcos

Being a teenager is hard enough. And what if your life's path is predetermined? On top of that, you aren't even Human?

Cayden was given life as a Cresecren. He expected to live out his days with the dysfunctional Human family he was assigned to serve. One fateful night, however, landed him in Gavaron, the home of maimed, elderly, or defiant Cresecren.

Beyond its borders is the Den, an area much more dangerous than he ever imagined. Now seventeen, Cayden unwittingly becomes involved in a conspiracy and is one of a handful of survivors fleeing a deadly attack. They set off on a perilous journey in search of refuge and the truth. Along the way, Cayden begins to comprehend the difference between fully living and merely surviving, while trying to balance his emotions and a forbidden love.
