The book blends elements of science fiction with authentic historical details and focuses on Simon Hathaway, a modern-day historian and Templar who has just been appointed Head of Abstergo Industries’ Historical Research Division in London.

In the story, Hathaway’s mission is to locate Joan of Arc’s sword, considered to be one of the Pieces of Eden, a relic with the potential to offer its user tremendous power over others. By connecting to Abstergo’s newly updated Animus, a machine that allows one to experience genetic memories of the past, Simon delves into the mind of his ancestor Gabriel Laxart, a farm boy who fought alongside and fell madly in love with the legendary Joan of Arc. With help from an intriguing French psychiatrist, Dr. Victoria Bibeau, and his tech wunderkind ex-girlfriend, Simon uncovers long-buried secrets that could threaten his present and have monumental effects on the entire Templar Order.

Launched in 2007, Assassin’s Creed videogames have sold more than 100 million units worldwide. The franchise is one of the best-selling series ever produced and is widely considered to have some of the richest, most engrossing storytelling in the industry.

Ubisoft will also publish a book on the upcoming movie on December 21, which is available here on Amazon, in conjunction with the release of the major motion picture “Assassin’s Creed” starring Academy Award nominee Michael Fassbender and Academy Award winner Marion Cotillard.

The film, directed by Justin Kurzel, is produced by New Regency Productions, Ubisoft Motion Pictures, DMC Films and The Kennedy/Marshall Company; co-financed by RatPac Entertainment and Alpha Pictures; and distributed by 20th Century Fox.
