Much as I actually read the synopsis once when I first saw it months ago on Goodreads and then again before I clicked "Read Now" on Netgalley, I ended up forgetting the synopsis entirely by the time I started.
Except for one word: Labyrinth. Needless to say, I actually thought for awhile that Gates of Thread and Stone would be about a labyrinth. The Labyrinth of the Greek myths, per say, and when I actually read Gates of Thread of Stone, I checked the synopsis again to set myself on the right track (because when there's no one being sent as sacrifice, you know there's something wrong).
Gates of Thread and Stone is really about a girl named Kai living with her "brother," Reev, in a place called the Labyrinth, named so by its maze-like structure, and where the lowest of the lowest in Ninurta live out their daily lives. But one day, Reev disappears – just like many others – and Kai is determined to find her brother.
There's something about Gates of Thread and Stone that I really like. It's definitely not the world, even though I highly enjoyed Lee's world-building – each section (East Quarter, White Court, Void, Outlands, etc.) in Ninurta were set apart from one another and most even had their own nicknames (East Quarter = Labyrinth, North Quarter = Purgatory). It's most certainly not the amount of possible f-bombs in here as well, or what I'll assume as f-bombs, because "drek" by itself is certainly not sounding like crap or hell.
The characters were tolerable – Kai is a determined and persistent character who has an admirable strength and may sometimes be a little feisty. Irra is perhaps one of my favorite characters by far, being a dramatic yet eccentric advisor in assisting Kai and Avan finding Reev. In fact... he's a bit of an oddity compared to the other Infinites, who seem to be similar to gods and goddesses based on their description.
The plot was a little predictable and I was just waiting for a couple of parts to play out (I really should stop being Sherlock Holmes and just enjoy reading the book, but I can't help myself). While the end is similar to the end of Senshi and the beginning of Shinobi and doesn't seem to have a bigger plot that spans over to the sequel or more books.
Now that I actually took the time to write all that down, maybe it's the world-building that I liked the most. With the ending of Gates of Thread and Stone seeming to be a solid ending, I may read the sequel just to for the pure fun of seeing what Ninurta will be like.
