Compare Earthbound (The Reach, Book 1)

The Earth is suffocating under toxic skies and there's only one way for those left behind to escape - the space elevator that sits atop the massive structure known as the Reach. Knile Oberend is an outcast, a man exiled for the crimes of his past. Thrown an unlikely lifeline, he has less than forty-eight hours to cash in his ticket at the top of the Reach and escape off-world. Disgraced cop Alec Duran had a bright future until he made one fateful mistake. Now his last shot at redemption becomes entwined with the fate of the very man who ruined his life three years ago. Alton Wilt, an underworld boss desperate to leave Earth, falls upon a rare find - the name of a man who is about to be granted passage off-world. With his minions in tow he is hell bent on stealing that privilege for himself. As time runs out, these three men find themselves on a collision course that will lead to a confrontation from which only one can emerge victorious.
