This is the first of Wade's books I've read, and I did really enjoy it. Here's my spoiler-free review!
Firstly, the world and mythos is very rich, explained in depth in dialogue as well as clever excerpts at the start of each chapter – something I do with my own books and a technique I really like. It's a good world, though with so much going on, and so much history, it was hard to keep up at points. Especially with so many characters coming in and out. However, I'm sure subsequent books will expand on it, which I'd like. Jak, the main protagonist, really carries the story through this world, and it's that personal investment that kept me hooked throughout. He grows with your own understanding of the world.
There's some of our own mythology mixed in, with clever twists, but Wade's also spent time crafting his own as well, which was very enjoyable to read. There're also elements of steampunk/dieselpunk, which I'm personally all for, and it's added in a great way that's not anachronistic or incongruous.
Description is one of Wade's strengths, and each scene is developed well with plenty of adventurous language. Sometimes, some of the descriptors seemed a little forced, but this is very minor and didn't distract me much. The action is nicely paced and well written, and there're plenty of bloody moments to keep my inner grimdarkian happy.
The story does flit around a lot, sometimes switching perspectives during scenes which might be confusing for some readers. The pace also changes frequently, however for a long story this is useful as you get breathing space between the action and information. It's quite a tome, so this is a good thing.
Overall, Genesis is rich, multi-faceted story set in a unique world with a strong cast of characters and a protagonist that's compelling. It's an enjoyable tale, and I'm looking forward to Book 2!
