As the Last Son of Krypton, Superman's always been alone on this planet ... and rare are the times that he's ever encountered someone who understands who he is and the choices he's had to make. But hidden away in the darkest corners of the Earth, rarely allowed into the light, there is another who sees right into his soul - someone who will force Superman to question everything he thought he knew about his life, his role, and the future he'd hoped to build! But with Lex Luthor on his trail and the mysterious cabal known as Ascension tearing the planet apart, he'll need to answer those questions fast because his adopted home is running out of time!
