Abe Sapien: Dark and Terrible Volume 1 — Mike Mignola

On the run from the B.P.R.D., a newly mutated Abe Sapien--more inhuman than before--travels across a United States transformed and overrun by monsters. Abe's search for the truth about himself--or his race away from his fate--mirrors the quest of an ancient necromancer to seize control of a world literally going to hell.

This digital book collects Abe Sapien volumes 3-5 (the beggining of the Dark and Terrible story), plus an expanded sketchbook section.
