J. Michael Straczynski's Midnight Nation v01 (2010)

Homicide Detective David Grey is lost. While trying to solve the most disturbing case of his life, he is unceremoniously cast into a crack between worlds: a shadowy netherworld where things and people -- lost, castoff or simply forgotten -- collect like dust in a corner. Now in a world where hopelessness reigns, his only chance for survival lies in an uneasy alliance with a mysterious woman who promises to either ensure his escape or kill him within a year.
