The Isle Of Blood - Rick Yancey

This is the third book in the Monstrumologist series.  And it was good as the others.  Dr. Warthrop goes hunting for what will be the greatest discovery in monstrumology Will Henry goes along on this nightmare journey. 

So far I think this is my favorite although it is hard to tell since I have really liked all of them.  I even convinced my dad to start reading them.  These are written for young adults and I would allow my young adult to read them.
