Rogue by Mason Sabre

Your son is missing, you’ve found a pile of dead, deformed shifters, and the person responsible is the hero foretold to save the world. What do you do?
Tammy Burch is a member of the True Order–a group of Others and Humans whose purpose is to restore Order, save the world and stop the one who calls himself the Prisoner from destroying it all.
But her son is missing.
Assumed to be on a training run, Parker hasn’t been seen for weeks. When his best friend turns up dead, and in a camp filled with dead and deformed shifters, Tammy fears the worst.
Panther shifter and dragon keeper, Tammy must go against everything she believes in, even if this means making her an enemy of the Order, if she’s ever to see her son again.
