Now their adventures are collected in one continuous saga, following the exploits of Abe Sapien, Liz Sherman, Roger the Homunculus, Johann Krauss, Kate Corrigan, Ashley Strode, and many more, from the war on frogs through the end of Ragna Rok. Join Hellboy creator Mike Mignola and a slew of talented writers and artists as they bring you the main collection of B.P.R.D. stories in a series of ten volumes"--
