BPRD Plague of Frogs HC Vol 1-4- So I think in the long run I’ve always given a healthy review for most BPRD projects, so I didn’t really plan to re-review this entire run. The thing is I was just in the mood to revisit the previous plots and character development since Vol 4 just arrived a week ago, so I made it a point to work my way through everything in about three days’ worth of reading.
