The Stars, Too Fondly (by Emily Hamilton)

Read for the category "a book set in space" and I think I would have DNF'd it otherwise. An easy read - it reads like YA, which is a problem since allegedly the characters are all postdocs - but right from the get-go, it's ridiculous.

A group of four friends (which conveniently includes an Asian man, a nonbinary person, and a Black trans woman - very YA-coded) accidentally steal a spaceship that blasts them into another solar system. This ship w" as supposed to go into space years before and "something went wrong" with the "dark matter engine and the entire crew disappeared, and then everyone on earth decided to just leave the ship lying around and not investigate it at all.  Definitely how science and humanity works! 

Then our lead character falls in lesbian love with the AI avatar of the captain, they watch a lot of 90s movies (very YA coded), and work to try and get back to earth, in implausible fashion. Sacrifices are made that have no real stakes attached to them. None of this is grounded in anything, or feels real whatsoever. It's just a light, breezy, very young adult read.
