Review by: ReadsWithCats
This is a 910 page novel and it has some mathematics in it, so it is a heavy duty read. Part science fiction and part historical novel it flips back and forth between WWII and almost the present day. During WWII you meet an eccentric cryptographer and his friend Alan Turing and a gung-ho Marine who occasionally serves with the cryptographer. During the present day you meet their descendants, who are also intertwined in each other's lives, as well as a couple of characters who are present in both timelines.
Stephenson is a very verbose writer. He weaves a large tapestry of details through several plot lines. If you like to get lost in a book this is a good one to pick.
