The Wealth — Richard Marman

Approaching his sixteenth birthday, Henry is thrust into a perilous quest when his village chief's wife is abducted. Joined by three companions and his pet wolf, he vows to track down the mysterious kidnappers. With no magic or special skills they can only rely on their courage, determination, wits and friendship to survive in a cruel realm that makes no concessions for youth or innocence. Danger mounts with each challenge until ultimately they face a seemingly unconquerable foe at the gates of a hostile, alien city.
