Raven's team has been tasked with ending the Inquisitor's menace, but how are they to do that when they can't even find the source of their power or destroy it if they could? Worse, they have very little time before things get really interesting for the world at large as the End of the World looms, except they need to find the keys to open the door...what a mess! But then an apocalypse isn't ever simple, straightforward, or easy, but then neither is any assignment assigned to the Lightwalkers. Hold on to your hats, things are about to heat up, quite literally!
