The book I read was The Monstrous Memoirs of a Mighty McFearless by Ahmet Zappa. The protagonist's name is Minerva. She has a brother, Max, and they live with their father; her mother is deceased.

In their father's study, Max and Minerva discover the Monstranomicon, a living book about monsters. The Monstranomicon bites Minerva, and its venom knocks her out. Her father finds that the children have been in his study, and he explains his occupation and warns them never to go into the study again. They, of course, ignore him. One day, a mysterious package arrives, and the next day monsters kidnap Minerva's father. Will Max and Minerva save their father? Read the Monstrous Memoirs of a Mighty McFearless to find out!
