I am blown away by Noah Lemelson's debut novel. I can't remember the last time a novel gripped me like The Sightless City did. The world building and creativity behind everything going on is top notch. You'll find yourself introduced to a new concept early on, and by the end you'll be so used to reading about it that you'll feel that it's always existed. The characters are all so well defined and interesting, too. Every single one of them is well thought out and feels real.
Finally, the tension in this novel is like none other I can ever remember reading. Several points I found myself unable to put the book down, or take my eyes off the page, wondering what would happen next.
