It;s ok, nothing special, the characters are what you expect, cliches and sadly not well used, in the far future modern slang still exists, culture problem still exist so future yet still in the present, deaf culture is a big thing in the story, deaf colleges being mentioned and people wanting to have hearing aids or getting a cure are looked down upon by a large part of the community, the main character's mother chooses to not let her kid get help with the matter as there is nothing wrong with being death even if her kid wants it....so great I guess.
I thought it would be mare about the effects of the signal however while it is mentioned the effects boil down to sex and violence, changes to the body are slightly studied and talked about however it's glossed over as being great!
The problem is that there is a lack of logic in the story, somehow this deaf person is allowed a position of the ship though you;d figure it would be a problem for them, the captain is a perpetual drunk, hurray for Russian representation, she had vodka breath is a thing in the story :) After picking up the signal these geniuses don't notify anyone else and run towards it, even our MC doesn't mention it, maybe let people know what we picked up? where we are going? you;d figure that on a small ship the crew members would double up on duties however nope, only the pilot knows to fly the ship if something happens then tough luck...
The ending does have cosmic horror to it, a big flavour of Cthulhu and some existential dread, if you take a step back from what is described you realize what utter horror awaits the people who end up there.
Overall I expected more from the story which it didn't deliver, I saw the problems from the early part of the book however I decided to move forward with it, I think I should have dropped it and switched over to another book. The ending did have cosmic horror getting there....could have been much better.
