Title: Lies and Truth - Nathalie Kuperman - book
Summary :
Today, Clarisse's life has changed because of a reading test. She handed in a blank copy to Miss Gorse, the CM2 B teacher. Clarisse doesn't like reading, but she likes zeros even less. And yet, that's what awaits her and what worries her. Because she's going to have to confess it to Mom, a sort of clairvoyant expert in secrets and hiding things. So Clarisse has an idea: she lies. Just a small, insignificant lie to dispel Mom's suspicions. She tells her she's angry with Anna, her best friend, and there you have it! Everyone knows that lies, even the smallest ones, always lead to bigger lies, sometimes terrible and painful ones. What if they also lead to the discovery of an incredible truth?
