What happens when an event causes all the Cullens to swap mates? How do they feel about this and who gets swapped with who?

When Violet is forced to leave her home as a group of cats takes over the neighbohood, she flees to EarthClan, where her mate- Nightblaze- is. She brings along her three kittens. But as Violet gets there, she is thrown into a prophecy! StarClan doesn't seem to care that she was once a Kittypet. She and her family are then in danger, since it seems to be around every corner! And when a cat from her past shows up, the whole clan is put to the test!
