Another student on campus, Lea Huckley, unknowingly shares Gabe’s obsession
with the fourth dimension. The monsters from the other side attacked her
parents and fled, getting her folks locked up in the loony bin. Proving this
other world exists is the only way to free them. Lea and Gabe strike a deal to
help each other, and together they manage to open a door to the world of Gabe’s
true origin. She’d use him for proof—if she didn’t already care too much.

While Gabe tries to reconcile his feelings for Lea and his rediscovered
memories of his fiancée, a much more sinister plot unravels. He uncovers his
history just in time to become the unwilling lynchpin in a conspiracy to start
a war. His memory holds the secret to the final riddle the would-be conqueror
needs to get the upper hand. Gabe must protect the riddle at all costs, even if
that means leaving Earth, and Lea, behind forever.
