A story called, The Balance. It's a YA novel set 200 yeas after an apocalyptic nuclear war in a place called the Land. The Land is ruled by a theocracy called the Council of God and they've banned most technology, so we have people who've lived in a modern world using horses and who've been forced to abandon anything that uses electricity.
The Land was ruled by a collaboration between the Council and another group called the Order (a technology organization), but it was discovered that the Order had been experimenting with an advanced form of genetic engineering, coupled with post conception manipulation of the fetuses to augment new characteristics. This caused the Purge of the Order and anything doing with technology and the execution of the engineered humans as demons. The main character, Phoebe, is one of these leftover engineered humans, hiding in plain sight and trying to deal with what the Order did to her.
I expect to publish The Balance in December and have published a prologue and 6 chapters on my web site michaelselden.com
