Challenger's Call series

When a freak accident ruins his body and his memory, Wes Malcolm loses his scholarship and his place in the world. Every treatment has failed, save one: a fully immersive VR game, designed by his late, disgraced father, that mimics the condition his body used to possess. To everyone's disbelief, his body and mind slowly improve, bit by bit, but it's still not enough. Then one night, he wakes up in a world just like the game his father designed. Here, he can grow, learn, and thrive.

The cry for Wes Malcolm's death has followed him 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 had rejected immediately. Now he needs to evade the monsters long enough to get the former hostages to safety, then grow strong enough to battle his hunters and win. To do so, he’s going to have to delve into the ruins of this world and discover ghosts and secrets from another age, including the hidden history of Earth itself.

Wes Malcolm has wrested Avalon back from men, monsters, and false gods. The next step is to bring the battle to his enemy's camp. The world of the Woadlands is under siege from two cataclysms at once. Fey of the winter courts seek to smother the planet in eternal frost, while an alien cancer gnaws at the ancient trees that power the magic of this world. Worst of all, his earthly enemies have spent the last 50 years making both threats far more dire, sabotaging the natives' every chance at survival. Even the planet's godlike Icons believe their world is doomed.
