A book of great depth and ideas, this explores the future ficitional history of humankind from our own generation until humankind's demise. The book does not follow the narrative of a single person, rather following the social trends of the different species of humans.

As a warning - this book took me three months to read. The subject matter is presented in quite a dry way, which resembles more a historical non-fiction than a sci-fi epic. This effect is intentional, but can make reading analogous to chewing cardboard.
