As the difficult times at school mess with Annas head, she needs to find out what's making her crazy. She faces stress. She has gotten grounded, band, and unfriended by many. How can she fix everything?Opinion/Rating: “Her Evil Twin” by Mimi McCoy was a very intense, fun, mysterious novel. This book is great for the dialogue. The way the characters talk. In the book after Anna and Emma meet, their conversations become very interesting, “I’ve never done that before” Anna admitted “I’ve never had the nerve.” “Stick with me” Emma said “You’ll be surprised what you can do.” Another conversation they had was, “You know I keep feeling like I’ve met you somewhere before,” Anna said. “isn’t that funny? What’s your last name?” “Diablo,” Emma replied. “Cause I’m devilish. You’d better watch out.” This book has a good point of view too, it’s told in third person. The person that is telling the story, is telling it over Anna, example: “Anna shook her head, realizing how foolish she appeared. How could she not have known where her best friend lived? And why hadn’t it ever occurred to her to ask?” The theme of the story is easier to figure out towards the late, middle part of the book. The theme can be different. Like, its about friendship, trust, or even likeness. It could be friendship because, “I said, if you want I can go with you. To meet Jessamyn after school today,” Dory replied. “Oh” Anna hesitated. Jessamyn’s note didn’t say anything about bring a friend. But she and Dory always did everything together.” I give this book a five out of five stars, for being a great read. I would recommend this for girls ages 10 and up. Anna is having trouble adjusting to middle school, and hanging out with her best friend Dorey doesn't help. Dorey doesn't care about being popular or about what she wears, and Anna is embarrassed to be around her. When the glamorous Jessamyn gives Anna a note to meet in a rarely used girls' bathroom, Anna is excited to be included in Jessamyn's secret group. When she agrees to take part in their initiations and "calls on the spirits" in the bathroom mirror, however, she faints. Jessamyn and her friends think that Anna is dopey, but it isn't long before Anna meets Emma, who is dangerous and cool. The two eat lunch on the roof of the school, throw balloons filled with catsup at Jessamyn, and even go off campus. Emma is a bit of a mystery, though-- she doesn't answer her phone, and is elusive about details of her life. She is also very jealous, and when Anna talks to Dorey and her new lab partner, Benny, bad things happen to them. Eventually, Anna is blamed for things that Emma is doing and starts to wonder: is Emma really her imaginary friend from childhood, and has she always been this evil?Strengths: Anna's angst about being seen with Dorey is so true to life, and this is a pleasantly creepy tale. The 6th grade girls at my school adore all of the Scholastic Apple series: Candy, Poison AND Rotten!Weaknesses: Not enough attention is given to why or how Emma has managed to manifest herself. I always appreciate a little bit of an explanation.
