After mastering the ability to walk between dimensions, Joey helped save the Altiverse from destruction.

But rival powers of magic and science are still out there, seeking to control all worlds. InterWorld's peacekeeping mission is far from finished.

And when a stranger follows Joey back to BaseTown things get even more complicated. No one knows who she is or where she's from and, more importantly, why she knows so much about InterWorld.
