Ethan Adams has always preferred the quiet rhythm of the band hall to the chaotic solos of center stage. A high school junior and self-proclaimed band geek, he's content to let the spotlight shine on his older brother, 19-year-old Danny, whose Down Syndrome has always been the dominant note in their family's symphony. With divorced parents—a father conducting a new, "perfect" life with a new family, and a tired, single mom struggling to keep their own orchestra afloat—Ethan often feels like a forgotten instrument in the background.

But Ethan's carefully composed world shatters when a tragic illness strikes, threatening to silence their family's already fragile harmony. As if life wasn't already off-key, the unexpected reappearance of Harper Martinez—an unconventional girl from his past—adds a surprising, yet alluring, crescendo to his days.

Can Ethan, who has always hidden in the shadows, step forward and conduct a path toward healing? Or will the dissonance of past pains and new heartbreaks overwhelm him completely?

My Brother, Danny is a poignant and powerful novel about finding your voice amidst life's unexpected rhythms, learning to embrace every note—both sharp and flat—and discovering that even the most broken melodies can lead to the most beautiful symphonies.
