This is an anthology of some loose, essay-like musings, a short story or two, and what I would call a novella. As such, Niven fans will enjoy these quick glimpses into some of his ideas about "life, the universe and everything" (sorry, but I really couldn't think of a better descriptive phrase!). The title story ("All the Myriad Ways," and if you couldn't figure that out you probably should stay away from this book) is, in my opinion, a sci fi classic that should be given to 6-8th grade students as part of their curriculum.
If you are looking for one of Niven's novels that draw you in, involving interesting characters and their even more interesting lives, this won't fully satisfy. But if you are in the mood for some light reading, or if you just want to get an idea of what Niven is about, then read it by all means.
This book of short stories contains one the best tounge in cheeck pieces of all time- "Man of Steel Woman of Kleenex" -about the problems of a physical relationship between superman and Loise Lane.
