The Monstrumologist

Yancey, Rick 

So starts the diary of Will Henry, orphaned assistant to Dr. Pellinore Warthorpe, a man with a most unusual specialty: monstrumology, the study of monsters. In his time with the doctor, Will has met many a mysterious late-night visitor, and seen things he never imagined were real. But when a grave robber comes calling in the middle of the night with a gruesome find, he brings with him their most deadly case yet.
