My New Book: Round Trip Puzzles

Available on-line and in stores as of January 4, 2011

Expanded Book Intro (online only) with in-depth solving strategies

A Note on naming: Round Trip puzzles are the same as Grand Tour puzzles (see below). Round Trip is the original name - I introduced Grand Tour at a time when I thought the name Round Trip might be reserved. I apologize for any confusion caused by this.

A Note on covers: The above is the cover under which the book will appear in January. You may see an older cover design at various on-line sites (these should eventually get updated).
