The Furies

Mark Alpert's The Furies weaves cutting-edge science into an ingenious thriller, showing how a simple genetic twist could have inspired tales of witchcraft and sorcery, and how the paranormal could indeed be possible.
For centuries, the Furies have lived among us. Long ago they were called witches and massacred by the thousands. But they're human just like us, except for a rare genetic mutation that they've hidden from the rest of the world for hundreds of years.
Now, a chance encounter with a beautiful woman named Ariel has led John Rogers into the middle of a secret war among the Furies. Ariel needs John's help in the battle between a rebellious faction of the clan and their elders. The grand prize in this war is a chance to remake the human race.
