Since I mentioned some funny CYOA-like smut that has recently issued from the IF community, I’ll also suggest a less lewd piece of branching narrative, one which allows the reader to make choices early in the text and in the story’s past: Andrew Plotkin’s The Matter of the Monster. Perhaps it’s a case of the folktale wagging the dog – in any case, it’s brightly written, cleverly put together, and worth reading.
