Summary/Annotation ->  Joey Harker is a hero. After mastering the ability to walk between dimensions, Joey helped save the Altiverse from destruction. But the rival powersâ#128;#148;one of magic, one of scienceâ#128;#148;who seek to control all worlds are still out there, and InterWorld's peacekeeping mission is far from finished. When a stranger named Acacia does the impossible and follows Joey back to BaseTown, things get complicated. No one knows who she is or where she's fromâ#128;#148;or how she knows so much about InterWorld. Dangerous times lie ahead for Joey and the mission. There's a traitor in the group of Freedom Fighters, and if Joey has any hope of saving InterWorld, the Altiverse, and the mission, he's going to have to rely on his witsâ#128;#148;and, just possibly, on the mysterious Acacia Jones. The Silver Dream is a riveting sequel to InterWorld, full of bravery, loyalty, time and space travel, and the future of a young man who is more powerful than he realizes.
