A review by englishlitlady
The Sandcastle Empire by Kayla Olson

4.0

Science goes whacky in the hands of anarchists when sea levels rise. Former rich kids end up in gulags, working to provide the tech needed for the former lower class now overlords to have a life of luxury and security despite climate change.

Except...

One girl - no, actually, FOUR girls! - escape the gulag! Search for amnesty on a mythical island, find it - the island anyway - and are promptly harassed by weird science, a lack of food and water, and boys. At least the one boy is cute. ;-)

Adventures ensue!

I really enjoyed it. Reminded me a little of the later Hunger Games with the whole pushing science too far and having hideous, twisted results.
