When Mockingbirds Sing by Billy Coffey

What marks the boundary between a miracle of God and the imagination of a child?
Nine-year-old Leah’s invisible friend seems harmless enough until he aids her in upsetting the tranquility of her new town, a place where her parents desperately hoped she’d finally be able to make friends and fit in. Hidden within a picture she paints for a failed toymaker are numbers that win the toymaker millions. Suddenly, townspeople are divided between those who see Leah as a prophet and those who are afraid of the danger she represents. Caught in the middle is Leah’s agnostic father, who clashes with a powerful town pastor over Leah’s prophecies and what to do about them.
When the imaginary friend’s predictions take an ominous turn and Leah announces that a grave danger looms, doubts arise over the truthfulness of her claims. As a violent storm emerges on the day of the annual carnival, Leah’s family and the town of Mattingly must make a final choice to cling to all they know or embrace the things she believes in that cannot be seen.
