Many great books have great sequels, some even surpassing the first book. Yet the debut author faced with a sequel faces some special issues.
The first book may have taken five years to write and a year to edit. The publisher will want to see the sequel within a year. Building on the audience is key – the book must build on what made fans of The First One like it, but not be a mere reheating. Certainly, it needs to be bigger, bolder… Widening it to reach new fans may annoy the existing ones. Fewer people will review the second, and they may have less compunction about being critical.
Sequels can be close or distant. Close sequels flow easily one to another. The Lord of the Rings was written as one book, divided into three by the publisher. Gene Wolfe’s Book of the New Sun follows the same protagonist through his quest with little gaps between books. Or, sequels can be more distant. Ursula Le Guin’s second Earthsea book, the Tombs of Atuan, starts in a different country with a different protagonist. Ged, hero of the first book, turns up half-way through as a foreign prisoner. In an extreme case, Adrian Selby asked to write another book in his Snakewood world chose to write one set two hundred years before, explaining the origins of a legendary figure in the first one.
Admiring Selby’s gall, there was never much choice for me. People who wanted to read a sequel universally want to know what happens to Gene, Molly and Cory, in the very different situation facing them after the first book. And I knew what that was, so I’m happily writing that.
