The Skrayling Tree: The Albino in America

The second book in “A Tale of the Albino.” When his beloved wife Oona is abducted by a band of albino Native Americans, Ulrik von Bek trails the group by using the Skrayling Oak. Soon he finds himself in the multiverse, where he is reconnected with his alternate self, Elric of Melnibone.

Don't know why, but I had a harder time getting through this book than any other Moorcock. Still good enough not to quit, though.
