Halley Harper is a walking disaster. Sure, she is full of science brain and fun ideas, but that's where it all goes wrong. Like how she nearly destroyed an oven cooking s'mores. And how her "monster toothpaste" experiment spewed green gunk all over her friend Gracelyn. And how the Monster toothpaste got in her hair and she ended up with a crazy new hairdo. One letter arrives soon: her favorite science magazine has asked her to interview a teacher at her beloved Camp Eureka! Halley BELIEVES this will be the time of her life--but not so much. Who's the girl with color-tipped hair who keeps trying to keep her apart from Gracelyn? Who is the crazy new roommate who talks nonstop? And why, oh, why is the camp magician sneaking around at night with a ripped-out page from her diary? This book is a perfect fit for every kid who has a science tornado inside of him or her that has to be let out. Extra plus for the science experiment instructions in the back of the book!Love this.
