Any Star Trek fan that appreciated post-modern fiction should pick this up. Structurally, I was worried when I realized the plot was coming to a solid close and there was another 100 pages left in the book. Then it veers heavily into postmodern style and provides some of the best writing and heart-wrenching pathos of the book. 
 Thematically it reminded me a lot of "So Long and Thanks for All the Fish". However, I think this delivered where Fish fell flat at points. The humor, pathos, and existential crisis is blended and delivered deftly. 
 Loved the Monty Python and the Holy Grail reference, as well as the All You Zombies joke.
