Let me start with something I posted in Facebook: If it can really happen, it is no longer dystopian but a warning.
This book is that and James Tarr is very good about it.
This is one of those books that requires you to pause every so often and breathe. It is both depressing and uplifting at the same time but very grounded in what reality could be. It will not take you long to realize that no matter how it goes, a Hallmark Channel-type happy ending will not happen in the book, maybe if the protagonists are lucky, they will get a respite.
