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. 'This latest spinoff from Mignola's Hellboy franchise continues the high level of modern weird tales-influenced chills and adventure and at times even manages to outstrip its source . . .' -from a review of a previous volume of B.P.R.D. in Publishers Weekly.
