Book Description from Amazon:
As if the world didn't have enough problems of its own, heaven and hell are gathering for the biggest battle of all---a 'forced' apocalypse started by none other than Morning Star himself. With an insane plan to prove that God isn't perfect, he enlists the help of a very jaded archangel, Michael, to help him with his scheme. Along for the ride are Apollyon, Lilith, and their legion of Destroyers--the children of the Watchers--and cataclysmic worldly events quickly unfurl as one lone city cop discovers he plays a pivotal role in how this 'apocalypse' will end.
