Warner Bros. has picked up the screen rights to a supernatural horror book series by Rick Yancey called The Monstrumologist. That book is just one of a four-part series, and the other books include The Curse of the Wendigo, The Isle of Blood, and The Final Descent.
The story centers on "Dr. Pellinore Warthrop and his assistant Will Henry. Will is an orphan under the care of Dr. Warthrop, who studies dangerous creatures and monsters. The story is set in 1888, when a nightmarish specimen is carted to the monstrumologist’s home — a vicious man-eating creature without a head."
I've never read any of these books, but that sounds like a really awesome story that has potential to be an awesome film. The studio has hired screenwriter Jessica Postigo (The Mortal Instruments: City of Bones) to write the script.
