Rene and Dante are dying. The soul they share cannot sustain them both, and they're quickly running out of time.

But Rene possesses a legendary chest said to contain the secret to eternal life-if only they could solve the clues that lie within it.

With the help of a mysterious letter-writer, they follow a series of signs that lead them on a treacherous journey across Europe, seeking a legendary chasm where souls go to be cleansed.

It's their only chance at a fresh start, but with it comes a terrible choice, one they never imagined they would be forced to make.
