Shiny new high school first-year Akira is as ordinary as they come. He's awkward, has terrible grades, and loves manga. In fact, the only thing that really sets him apart from his peers is his staunch determination to follow in his late father's footsteps as a police officer.

But fate has its own plans for Akira. After witnessing a ferocious battle unfold between two strangers with unusual powers on the train—one of whom looks a lot like the tall, dark, and handsome kid in his grade—he finds himself kidnapped...by none other than an alien! And as if being thrust into the occasionally violent and always complicated relations between humans and aliens wasn't mind-boggling enough, nothing can prepare Akira for learning the truth about his beloved father...

Three years ago, a gateway between Earth and the Beyond opened over the city of New York. In one terrible night, New York was destroyed and rebuilt, trapping New Yorkers and extra-dimensional creatures alike in an unassailable island, a world all its own hidden in the mist of its physics-defying waterfalls.

New York has been rechristened Jerusalem's Lot, a paranormal melting pot where magic and madness dwell alongside the mundane, where every form of human vermin gathers to exploit otherworldly assets for earthly profit. Now someone is threatening to breach the controlled flow of unharmful, average humans and items in and (much more rarely) out of the city and thereby release Jerusalem's Lot's deluge of horrors on The Outside. The mysterious super-agents of Libra fight the impossible to prevent the unthinkable.
