The Aliomenti Saga: Preserving Will by Alex Albrinck (book 5)

Book 5 - Preserving Will:

He's provided for each of them the opportunity to lead a life of health, wealth, and power far beyond their imagination. By his own example, he's shown them that such gifts are meant to be shared, used to make the world a better place. And he's never asked them for anything in return, showing a willingness to risk even his own life to live to his own ideals.
Now Will Stark needs their help. He's helpless, he's uneducated, and he's about to meet men who can utterly destroy him.
