I'm losing my mind with so much of this.

There still are far too many blatant Hitchhiker's Guide references, which makes me feel like I should just read that series instead. There's a Gneiss elder (who is a ship) who... recites poetry to everyone who boards, which is reminiscent of the Vogons who recite poetry to stowaways.

The most interesting names for aliens are those that the author points out as "sounding Indian" (Devanshi), which... that's definitely a look. Others are named Tina, Algernon, Ren, and Osric. None of them have names that sound like a version of 'space'. Again, if your influence is Hitchhiker's (as the acknowledgement stated), then... you had an example of fun names! And you could've played with names to have fun. (Other alien names are mostly nouns, like a space station named 'Eternity'.)

As a mystery, it's... not. If this was a "sci-fi thriller" or something in that area, I'd probably be less annoyed (even with the excessive references). But so far, I haven't found anything resembling a mystery. It's like Lafferty read one Agatha Christie book (And Then There Were None), thought that because it had shifting perspectives... that's how it always was. But even so, she didn't learn the mystery element at all. There are no real clues and all the questions are asked and answered almost immediately. Things are hidden for giggles (it seems), but it's not obscuring it for a mystery's sake... The people in the praise-for-the-book section talking about how it's the "sci-fi version of Agatha Christie" clearly haven't read Christie (and if they did, didn't understand why her novels were actually engaging and were really good at building a mystery for the READER TO SOLVE... which is the key part of a mystery).
