Publisher's Synopsis
Joey Harker isn't a hero. That didn't stop him mastering the ability to walk between dimensions and helping to save the Altiverse from destruction. But the rival powers of magic and science still seek to control all worlds and InterWorld's peacekeeping mission is far from finished. When a stranger named Acacia does the impossible and follows Joey back to Base things get complicated. No one knows who she is or where she's from - or how she knows so much about InterWorld.
