Gabimaru the Hollow is one of the most vicious ninja assassins ever to come out of the village of Iwagakure. He’s ruthlessly efficient, but a betrayal results in him being handed a death sentence. There is only one hope: travel to a long-hidden island and recover an elixir that will make the shogun immortal and he will regain his freedom. Failure is not an option—on this island, Heaven and Hell are a hair’s breadth away.
