"In 2001, Hellboy quits the B.P.R.D., leaving its roster of special agents to defend the world from any occult threats and the growing menace of the frog army. 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."--
