Brace For the Wolves (Challenger's Call Book 2)

Kill the traitor-prince.
The cry for his death has followed Wes Malcolm from Earth all the way to Avalon, and an entire new breed of Hordebeast has taken up the call. Howling wolf-men now hunt him as an escaped convict, a false teacher, and a traitor to a legacy he has rejected. Worse yet, he must fight not only for his own freedom, but for the prisoners he has rescued from the dungeon on this ruined world.
Now all he needs to do is evade the monsters long enough to get the former hostages to safety, before taking on and defeating the hunters. To do so, he’s going to have to delve into ghosts and secrets from another age, including some explosive secrets of his own heritage.

He cannot fall here. Too many worlds have put their hope in him.
