Assassin's Creed (book series)
The Assassin's Creed series, by Oliver Bowden, is a collection of novels set within the Assassin's Creed video game universe. The books follow various assassins who become involved in the war with the Knights Templar.
Renaissance
The first novel of this collection, Renaissance, was published in 2009. The novel features Ezio Auditore da Firenze, a man who seeks revenge for the murder of his family. Ezio begins to train himself as an assassin and becomes drawn into a war between the Assassin's Order and the Templar Order. The two secret organizations have been combating each other for centuries to secure an ancient technology, called the "Apple of Eden," a relic which can control human minds. Both groups also seek a vault in Italy, which contains the knowledge and technology of an ancient, technologically superior civilization.
Brotherhood
Brotherhood—the second novel in the series, was released in 2010. It's a novelized version of the popular game Assassin's Creed: Brotherhood. Just like its previous book, Assassin's Creed: Renaissance, it does not contain any of the game's present-day events including Desmond, only a reference to a "phantom" by Ezio. The story takes place four years after the video game's story(1499), in 1503. Ezio Auditore struggles to free the city of Rome from the tyranny of Cesare Borgia, who seeks to take over Italy.
