Shy, eleven-year-old Lily made her dad an important promise before he passed away--that she would "Strive for Five" and speak her mind at least five times. But speaking up one time, let alone five, is easier said than done. It'll be even harder now that Lily must attend public school for the first time. Fortunately, she meets curling-obsessed Hobart and quiet Dunya at the beginning of sixth grade. Their kindness gives Lily hope that life without Dad might just be bearable. But when Lily and her friends are bullied by Ryan and his mean clique, she quickly discovers the true meaning of friendship and speaking out. Despite the anxiety she feels, Lily knows she needs to stand up for herself and others. And she'll use the tools her dad gave her to not only keep her final promise but bring her whole school together.
