This is the only book I've ever read that I think I might actually have been better with an abridgement. The story is great and the language is beautiful, but over the course of the story, too much attention is given to supplemental chapters about technical details and historical information about whaling in general. While it may be interesting to some, many of these chapters add nothing to the story of Ishmael's adventures on the Pequod.
Engrossing first half but by the end I felt really underwhelmed like nothing much worthwhile resulted from an otherwise interesting premise.
The writing and the story are good, but what makes this novel special is the world that Gibson created, which is essentially the source code of the cyberpunk subgenre.
