Carver hates that he still works for the Alliance of Dimension Travelers. But he's gone into debt to provide for his family, and deserting the army would also mean deserting the only home Carver has ever known: Kristi. As escape seems less and less likely, an old acquaintance contacts him with a desperate plea for help. Dimension Earth 12 is in trouble. So is a closed-off world called Lenovra. The Ex-D have a new ally with abilities that defy explanation.
