This book is one of the best books of the Goosebumps series ever. Monster Blood is scary and the writer makes the story mysterious. Both of the main characters are brave and try to solve problems throughout the book. The author makes me wonder what I would do if I found a mythical substance.
I recommend this book to people who like spooky spine chillers. Kids of all ages will be put in a scary mood.
