The Sindicate - The Associate, #2

Nate Holliday and his girlfriend, Melanie Sarkosian, are back. This time, they're fighting crime across the great state of Portland. While earthly law and order is Nate's main focus-that, and graduating high school-he is soon contacted by a representative, Titanic Man, a member of a crime-fighting group from a parallel Earth. It seems that trouble is brewing on Earth-Seventeen, a world similar to ours in terms of clothing and design, but with more advanced technology.
It seems that one member of the good guys has been captured by the opposition. Ukiko Monaghan, also known as Dividing Woman, has gone missing, and Nate and Melanie are the only ones capable of bringing her back. It won't be easy. Ukiko has fallen in with-or been taken captive by-Alvin 'Big Boy' Larpis, the most feared gangster who sends his minions to various Earths in search of materials to build the ultimate weapon.
However, when Alvin sends a hit squad to Nate's and Melanie's home world, things get darker, more personal, and Nate has to make a terrible choice of seeking vengeance or upholding the law.
