Heresy is set in the universe of Assassin's Creed and through it we relive the memories of high-ranking Templar Simon Hathaway's ancestor who fought beside Joan of Arc. He slowly uncovers secrets of the past that could dangerously impact his present and that of the entire Templar order. An endless conflict. An old wrong. A new revelation.
I really enjoyed reading Heresy and from all the books that I have read in this universe this is a little bit different from the normal Assassin's Creed style. It is written in a different style and it combines the present day London and Abstergo with the past (when Joan of Arc lived).
The world building was good and it shows the medieval/renaissance world with authenticity and does set the scene really well. In terms of characters I liked the modern and historical characters. I really liked all the modern characters and found they really had a story of their own. The plot was well paced and had a lot of action. Lots of battle scenes as you would expect but also some good character development. There was also some surprises and shocks.
It may sound weird but in this book, I liked more the parts of the book that had to do with the present. Finally I liked the ending which was something I didn't expect. (
