Book excerpt: Like its triumphant predecessor, the first volume in David Copperfield's ongoing collection of tales by his favorite writers, this is far more than just a book. It is a dazzling miracle show in which some of today's most celebrated authors have been summoned onstage and asked to perform their own special wizardry for a legendary performer's millions of dedicated fans. This second "invitation-only" volume includes such masters as Neil Gaiman, Peter S. Beagle, Anne McCaffrey, Tad Williams, Greg Bear, Katherine Dunn, and the Grand Illusionist himself.
