Query: A wonderful book.

Be careful as you read to avoid associations with Roger Zelazny's Amber Chronicles, with which it shares many elements: multiple universes, a larger-than-life family full of political intrigue, powerful magic, first-person viewpoint. But unlike Zelazny's Corwin, Willey's hero is young, inexperienced, and uncertain of his place in the Grand Scheme of Things. He makes mistakes, steps on toes, and -- most endearing -- loves his mother.Before you conclude that this all milquetoast and romance, I should point out the rollocking adventure, powerful magic, and especially the sense of mystery that pervades the book.Hopefully, this will come back into print. It's one of my favorites, and I hate to think of what will happen when my well-thumbed copy disintergrates.
