This was a really unsettling book to read one month into Trump's second term.  The book talks a lot about rot in the world making everything worse. 

In some ways it's too easy an answer, of course.  People aren't entirely responsible for the bad things they do or say if they're influenced by corruption.

I really liked all the characters.  They felt very real to me, especially Sal and Zelda's complicated relationship.

I also like the setup of how traveling to alts worked, and the alts themselves were interesting, and terrible.  The knacks were really interesting too. 

I also really liked the explanation for why the alts were all so terrible.  That was clever.
