Dream on, Amber / Shevah, Emma

An eleven-year-old half-Japanese and half-Italian girl named Amber worries about making friends at her new school, and misses her dad who left when she was little. So Amber creates an imaginary father who's a secret agent and writes letters from him to her younger sister, Bella. Things quickly spiral, and Amber's good intentions get her in trouble.

Amber's Japanese father left when she was little, and her sister Bella was just a baby, so now she fills in the frustrating gap in her life with imagined conversations, and writes letters to Bella that seem to come from their father.
