2.5 stars.
I'll be brief because honestly I don't have much to say.
I haven't played the game yet, because I was wary of its length, structure and more RPG-oriented gameplay, but as I'm currently playing Origins and I'm ejoying the changes thus far, I thought maybe I should give Odyssey a try in the near future. Now, after reading this book, I might not give anything a try any time soon. Not soon, at least.
It is indeed better written in my eyes in comparison with Bowden's books; but the fact remains that it still poorly written. Doherty has a good eye for descriptions of places and scenes, but fails miserably at dialogues, descriptions of people and pacing. Many important things happen "off-screen" and he tries to instill some suspense by cutting the scene and transitioning to a different point of view to give us more crescendo - only to fall on nothing because the build ups are not well paid off. I've read somewhere this book is a DIRECT adaptation of the game, like, it leaves nothing out of it, but it also adds nothing. It's not like in previous books where sometimes we would get some after game/before game events or a different perspective (Unity through Élise's eyes, AC3 through Haytham's eyes). This book is the game and nothing but it, so it doesn't compel me so to play it afterwards, since I already know everything.
I did find Deimos/Alexios' motivations lacking, I hope that's not the same in the game - he does come across as a brat who's only evil for the sake of it. Boring as an antagonist.
I didn't learn anything new for the AC lore of the precursors or neither of the conquesting orders.
It started out strong and with a nice pace, but halfway through it I checked out from the story hard and during the last chapters I just didn't pay attention at all, which is a sin for any reader.
That ending was anticlimatic, huh. Though I don't know of which "climate" i'm talking about since half of the book lacked any kind of emotion or connection with the reader.
When you just describe events instead of living them - and in turn, making the reader live them as well - you know you're just not a good writer, or you're not enjoying what you're writing. I think the latter is what normally ocurrs when an author is hired to write videogame adaptations. And sadly we, fans, pay the price.
