Incredible world building

I can completely understand why people have a “Marmite” reaction to this (i.e. they either love it or hate it): if I hadn’t read the prequel to this, All Bleeds Through (ABT), then I believe that I would have been somewhat confused, too.
ABT lays out the basics of the universe, with tales set inside it that eventually all link together. This brings nearly all of those loose threads together, and shows how much each individual and story really are connected. When I realised this, I had to go back and check, and I was wowed.
Not only that, the mythology is set up brilliantly. We not only have the Hemomancers and Humans, and how they are affected by events and each other, we also have a whole background of religious mythology with such amazing depth to it, that it’s completely believable that it could be our world and not just an alternate universe.
As for the story itself, here we have Coral, and Gavin, alongside other characters who were introduced to us in ABT. It is primarily Coral and Gavin’s histories which are revealed here as being important to the story as a whole, neither of whom actually truly knew about their background and the true meaning of it.
Coral goes from being a scared, ambivalent teenager, to a strong wildcard contender. She’s supposed to be a “nought”, one with the blood type O Negative, who has no control over the blood of others. Yet there is a huge fight over her blood; in the hunt to kill noughts over the years, Coral is now perhaps the only one left, the only one who can save an evil lord whose blood was poisoned years ago in order to end the slaughter.
But, this is where it gets complicated for Coral: who is the real monster in this story? The lord who has tried to control all other hemomancers for more than a century? Or those willing to sacrifice Coral for the greater good?
Can Coral not only prevail but find a way to fight back? It’s not until the very end that she finds out who are true friends are, but by that time, will it be too late?
I must admit, my rating hovered back and forth on this, mostly due to the characterisation. But it all came together wonderfully, as the characters and the story developed. Most of all, towards the end, it was possible to understand the characters and their reasonings better. The ending was a total shock, but shouldn’t have been so surprising, really. No one is safe and what can go wrong, will go wrong, etc. So, along with all of the above, I just have to rate it highly, just like the prequel.
The final lines leave hope, despite the devastation. A nice way to make way for the sequel.
Final rating: ★★★★★ – Loved it/couldn’t put it down
