This is the first B.P.R.D. trade paperback containing one long story, rather than a collection of stories. These are the issues that got B.P.R.D. its own continuing series, much like the Hellboy collections. It is also a great story with some important revelations for the Hellboy universe and its characters.
Be aware that although Mike Mignola drew the cover and wrote the story, the pencils were done by Guy Davis. In my opinion, if Mignola wasn't able to draw it, Guy Davis would be my next choice for anything Hellboy-related. However, Davis's art style is fairly different from Mignola's, so keep that in mind.
The Highlights: Great story, great art, and lots of tie-ins to the Hellboy storyline. The origin of Abraham Sapien is revealed! (though of course it raises many more questions). This story features the frog monsters and Rasputin from the first Hellboy story (Seed of Destruction). It also has an afterword by Mike Mignola and an eight page sketchbook of Davis's work and some of Mignola's notes.
Things to Consider: The story comes to a close, but it doesn't tie all of the loose ends up. This is because the story of the B.P.R.D. continues in other volumes. It left me wanting more, but not disappointed. There is also a little bit of recapping Hellboy stories that relate to this story. It didn't bother me in the slightest, but some people are bugged by that sort of thing. I felt like those parts added context to the story and didn't take up much space.
This is my favorite B.P.R.D. collection so far (out of 1-3), and it left me excited to read more! If you are worried about prior knowledge, this one takes care of that for you, and whether or not you know a lot about the B.P.R.D. it is a fun read! There should be more comics with giant fungus creatures and evil frog men!
