Amaryllis, by Carrie Vaughn

Amaryllis is a nice Green tale, the unwanted child making good.  In this case it's pretty serious, as we are in the severely resource-constrained future and extra children are considered deadly.  But it's not the kid's fault.  It's a fairly vanilla picture of that future--the seas still produce, and there is general agreement on how to live, so as dystopias go it's not too bad.  Authorities are even reasonable and fair, which could make it qualify for a utopia.  It's a sweet thing.  3 stars.
