Having read the first book (Solomon's Thieves) of this 400+ page graphic novel late last year, I was simply relieved that my public library purchased the entire book as I cannot find a listing for either books 2 or 3 mentioned anywhere. Yes, this is a lengthy graphic novel, but don’t let the length dissuade you.
For the most part, the book was an entertaining swashbuckler. The overall storyline has a good mix of action and suspense with a dash of romance but the political intrigue is quite tepid. In this sense, I was disappointed. To me, one of the greatest medieval mysteries is not what treasure that the Templars were hiding but why the Templars were caught so off guard by the political maneuvering that led to their members’ arrests and the eventual disbandment of their order. All we get as an explanation is that the French king covets the wealth of the Templars and wants it so he can pay his army to fight in an upcoming war. As a result, the story becomes essentially a heist, ala a medieval Ocean's 11 (note: I only counted 7 would-be thieves in the book so really it's more like Ocean's 7).
As for the characters, I have to admit that I was not a huge fan of either Martin or Isabelle, the hero and heroine. Perhaps it is because the reader is left wondering about their past romance. You are simply left with some vague misunderstanding between the two leading her to believe he abandoned her to join the Templars and him thinking she married for money. When the two meet again after so many years, they spend more time bickering about past grievances that it was almost difficult to see why fell in love with each other in the first place. Even the introduction of Bernard as a potential love interest for Isabelle which is meant to fuel Martin's jealousy, was lost on me as I personally thought Isabelle did not need either of these two men in her life. From what I could tell, the author did such a terrific job of portraying an independent strong-willed heroine that in some ways, the "twist" at the end should not have come as a surprise. In any case, the character that I wanted to read more about was really Salim whose self-imposed exile and dogged determineness to help his fellow disgraced Templars to steal back the treasure made him a much more intriguing character.
If someone was looking to read a good historical graphic novel set in the Medieval period with a focus on action and suspense, then you should check out this book. Even though the publisher is marketing it towards a young audience, I think adults will enjoy it as well.
