Franny K. Stein Mad Scientist

Hi guys I just read an unbelievable book. It was about about a girl named Franny who love to do challenging projects. Franny made a mummy that ate a custodian worker. Afterwords Franny had to unzip the mummy so that she could get the custodian worker out. I would like to recomand this book to people who loves to read books about mad scientist.
