The letters she writes to her imaginary friend, Grace, help her cope with the difficult times in her life - her mother's sad days, their money worries, the pressures of not fitting in. On her eleventh birthday, Hope is shocked to learn that Grace is real. Hope decides that by finding Grace, their family will be healed. But, like most adventures, things do not go exactly as she hopes.
