Too Like The Lightning by Ada Palmer is ambitious, complicated, excellent, and only half a story.
If I had to compare to any other work, I’d say it’s closest to “The Book of the New Sun” by Gene Wolfe.
The narrator plays with us. He addresses the reader, as Dear Reader, and the delivery and reveal of information to us as readers is extremely deliberate–even though it’s a relatively chronological story set over only a few days. At one point, he mentions that it’s silly that the word “visor” isn’t spelled with a z, because visors are futuristic. Chapters later, he spells it vizor.
The sequel comes out any day now, and I’m really excited to read it.
