Gr 3-5-When Masha Sweet wakes up with flowers stuck in her hair and her head glued to a pillow, she knows her sister, Sunny, aka the evil genius, is to blame. Because there isn't enough time to get the glue out of her hair before school, Masha's mom lets her stay home. In addition to dealing with her super-smart, super-annoying younger sister, fifth-grader Masha is having a hard time making friends at her new school following her parents' divorce, so she is more than willing to skip class. Masha soon discovers her neighbor, Mrs. Song, has fallen off her bicycle in front of the house. Sunny is there moments later, and when the paramedics arrive, the girls ride along in the ambulance. At the hospital, high jinks prevail as Masha's arm is mistakenly put in a cast and Sunny gets her in all kinds of trouble. When Masha meets some of the kids at the hospital, she discovers how lucky she really is, even if her sister drives her crazy. While some of the events that take place in the hospital are hard to believe, children will be able to suspend disbelief. Although the main character is in fifth grade, this book will find fans among younger readers. Black-and-white illustrations contribute to the humor in this tale of sisterly adventures.-Sarah Polace, Cuyahoga Public Library System, OHα(c) Copyright 2013.

"If you love Beezus and Ramona...You know that having a little sister whose purpose in life is to annoy you is hard... and hilarious. In Sunny Sweet Is So NOT Sorry, Jennifer Ann Mann balances the characters' worries (being new at school, their parents' divorce) with humor." - Redbook "Debut novelist Mann hits the sweet spot for lower middle-grade realistic stories, keeping company with the masters--Clements, Blume, and Cleary. Long-suffering Masha Sweet has an evil genius for a younger sister, six-year-old Sunny: "She was born brilliant...she'll invent some poisonous gas that will snuff out the sun and freeze us all into human Popsicles, but until that time, she seems perfectly content to practice her evil schemes on me." Your young humor fans will be thrilled to learn this is a start of series...." Jill M. Barton, MLIS, Collection Development, Ingram Library Services"This book is SUPER cute. I read it to my girls and they loved it. My oldest said that she wished there was a movie about Sunny and Masha Sweet! I would gladly recommend this book to young boys and girls. It shows the ups and downs involved with having a sibling, while making you smile through the whole ordeal." Books For Kids"For kids with a zany sense of humor, Sunny Sweet is So Not Sorry will be a real treat. From beginning to end, this book is unpredictable, with silly surprises lurking in every chapter. Girls who have pesky younger siblings will relate all too well to Masha's frustrations with Sunny's mischievous behavior, but they might also appreciate their own sisters that much more when they realize how much worse their situations could be!" Katie Fitzgerald, Secrets and Sharing Soda"There were so many great characters in this book and a lot of lessons for the young readers to enjoy. I'm looking forward to what sort of trouble Masha and Sunny will be getting into next." The Paperback Princess
