1988151 pages. Artist Robin Wood met Anne McCaffrey at the first totally Pern-oriented convention in the U.S. in 1984. However, prior to that, Robin had designed and executed portraits of Pern characters for the Mayfair Games board game, Dragonriders of Pern. In the ensuing conversation about what the characters from the Pern books really looked like, this book was conceived. Four years of work followed, with Robin and Anne comparing notes at conventions, discussing details of Pern and its people, passing letters and sketches across the Atlantic and arriving at mutually satisfactory conclusions. This represents the first, authentic look at the people of Pern, a collaboration of the finest kind between two of the finest artists available today.

1993172 pages. "Aboriginal heroes are everywhere... Who is Yours?" With these words, the Aboriginal Heroes Contest on which this book is based was introduced to students and teachers across Canada.

Aided by this book, teachers and parents can communicate to students that everyone has something of the heroic in her or him; that everyone can think deeply and feel deeply about issues of importance; and, as a curricular consideration, that everyone can learn to express those feelings in thoughts and written words.
