B.P.R.D. The Warning

The team tracks down the mysterious gentleman who's been appearing in Liz's visions, but soon find themselves in over their heads when old enemies-from the frog creatures, to the Black Flame, to the last denizens of Hyperborea-descend to lay waste to the world.

 B.P.R.D.: The Warning is the first of three explosive arcs pulling together threads from throughout the series-and leaving the B.P.R.D. and the world forever changed.
