Not A Wake: A Dream Embodying π's Digits Fully for 10000 Decimals
   A collection of short stories, poetry, plays, puzzles, and other surprises, all constructed according to the rigid rules of "Pilish", that peculiar variant of English in which the number of letters in successive words is required to follow the digits of the number π = 3.141592653..., in this case for a truly grand total of 10,000 decimals.  The perfect book for fans of the number π, constrained writing, wordplay, puzzles, or experimental prose and poetry.
