I can't believe The Obsidian Blade is rated under 4 stars on Goodreads! It's one of the best books I've read so far this year. I absolutely adored this book!The Obsidian Blade has such a complicated and well thought out plot, it kept me hooked from the very beginning because I need to know more about what was happening. I was drawn in from the very beginning, when Tucker's father disappears for the first time. After that, I couldn't put the book down.The world building was my favourite part of The Obsidian Blade. It was complicated and so well written that it's probably one of my favourite science fiction worlds! The whole thing about the diskos was fantastic, the history behind it and the different rules were things that I loved reading about. There were so many plot twists thrown into this book, I had no idea what would happen next. I was totally gripped as I was trying to figure everything out before it happened, but I was proved wrong again and again.I loved all the characters, even the antagonists. I'm really looking forward to seeing more of Tucker, Lahlia and Kosh if/when the next book comes out. I'm wondering if we'll see Tucker mature more after everything that's happened to him and... Well, that would be a spoiler!Pete Hautman's prose is flawless. Like I said, I was kept completely hooked, and I think a lot of that had to do with the writing style. There is one scene in which Tucker goes through a disko and is thrown into a situation in which he could well have died. I was holding my breath through the whole thing because the descriptions were so vivid.This is an AMAZING book, and I think everyone should read it because I'm sure you would really enjoy it too. If you're a fan of sci-fi then definitely give it a go!
