Narration was great. Story pretty much just turned into background noise for me. I waited the entire book for an explanation on how intergalactic bugs that hunted on par like a pack of wolves were intelligent enough to build starships and navigate the solar system. Figured they were a precursor for a more intelligent species to wipe out the planet for their arrival, but that explanation never came, not even in the epilogue. You’re listeners aren’t stupid. Ask smart questions in your books.
