What's Your Callsign? by Michelle "MACE" Curran

She fears what her classmates will think, and worst of all, what failures mean about her. After all, a recent blunder on the soccer field earned her an unwanted nickname.

As she runs home embarrassed by her performance, her fighter pilot grandpa helps her view failure, and her nickname that came from it, in a new light.

What’s Your Callsign? Is a story written to help kids learn the power of failing. Lilly learns that all fighter pilots have callsigns–– nicknames based on a mistake they made––and this gives her the confidence to learn from her misstep and try again.
