I just finished the Christian future tech/dystopia book "Mission Trip", advertised here, via Kindle Unlimited and found it very good. Its sequel, Mission Trip: Genesis and Exodus is next on my reading list.
I also recently read "Starlight", a Christian sci fi/romance book that is likewise on Kindle Unlimited and advertised here, and found it good.
The ads here don't allow comments, so this will have to serve instead.
