This reminds me a bit of Illuminae with the space setting. Except Illuminae does it soooo much better. I never fully got into Defy the Stars. The audiobook was tough to get into as I hate when they have two narrators but don't use it for the character all the way through.
There are robots, an interstellar wars and of course a romance brewing. The ending didn't do too much to hold me over so not sure if I will read the next one.
