On the one hand, there's a lot to like here. It's not shy about homages to pulpy sci-fi, not afraid to be over the top, fresh worldbuilding...
On the other hand, it's full of prose gaffes like this:
"Around me, the white wastes stretched around, a flat surface broken up by the ruins stretching a mile around us."
YIKES
Lots of stuff any editor worth their salt would have caught. I can knock off at least a star for that.
Speaking of editing... the narrator spends about 25% of the book navel-gazing, walking us through mundane processes, explaining every decision from every character, etc. While listening to the audiobook, there were times where I said "shuuuuuut the fuck upppppp" out loud.
Also, no spoilers, but the arrangement is off. The emotional and plot climaxes are in the wrong places in the big picture, and there are loose ends and Chekhov's guns that never go off. It ultimately gives an awkward feel to an opening series arc that could have been nicely wrapped up.
BUT IT WAS COOL SO 3 STARS
