''The Eight'' is a novel by American author Katherine Neville. Computer scientist Cat Velis becomes involved in the search for a legendary chess set, the Montglane Service, once owned by Charlemagne.

!!Tropes:

* ActionGirl: Catherine and Lily, but the most amazing one is Mireille.
* ArtisticLicenseHistory: Of course. Just a few: Basque people were never a menace for the Carolingian Empire. The rules for the Mad-Queen Chess, or modern chess, are from the XIV century, making it impossible to have a Chess Master associated with Charlemagne. In fact, in that era, there was no queen at all, but a piece named Vizier.
* BabiesEverAfter: [[spoiler:Cat and Solarin had a daughter named Alexandra Solarin who is the sequel's protagonist.]]
* BigBrotherMentor: Nim to Cat.
* BigBrotherIsWatching: Nim could fit into this since he is always one step ahead.
* CharacterDevelopment: A lot! Lily starts as a SpoiledBrat and changes to [[spoiler:ActionGirl / SpoiledSweet]].
* ChessMotifs: The whole plot of the book.
* CrazyPeoplePlayChess: One minor player insists that, when he captures a piece, a spectator be kicked out of the room so that the room's 'symmetry' is maintained.
* DarkIsNotEvil: The main characters in the first book are on the black team. Cat Velis takes over from [[spoiler:Mireille]] as the Black Queen. The antagonists are all on the white team. In the sequel it gets a little more complicated.
* {{Doorstopper}}: 624 pages in the paperback edition.
* GloriousMotherRussia: The book's two parallel storylines are set in the Cold War and (in part) in Catherine the Great's Russia.
* HistoricalDomainCharacter: Almost everyone featured in the earlier timelines of both books.
* HistoricalVillainUpgrade: The villain of the French Revolution timeline turns out not to be Talleyrand. It's not even Robespierre. It's [[spoiler:Marat.]]

* SignificantAnagram: Gaelen March is an anagram for Charlemagne, first tipping Alexandra off that he's more than he seems.
* SignificantBirthDate: The main character was born on April 4, which ties in with a lot of the book's numerology and is also said to be an Islamic holy day.
* SmartPeoplePlayChess
