Dr. Abby Corman has a bold idea: open a stable doorway between our world and an uninhabited parallel Earth. A new world we can use to mine resources to end poverty, grow enough food to end all hunger, and allow for population growth to end overcrowding. What could be a more noble aspiration for a brilliant young scientist? But the path to hell is paved with good intentions....

The Gateway Project was going to save our world by opening up a doorway to infinite versions of our planet. But the threshold has gone completely out of control, sending all those other Earths onto a collision course with ours. Now, our reality is cracking apart. Abby Corman did not open the Gateway, but she is the only one who knows how to close it. But an alien Hunter and her pack of deadly hellcats have stepped into our world, and they will stop at nothing to kill Abby.
