When a bullied teenager bonds with an 89-year-old jazz musician a beautiful friendship begins in a novel that celebrates the power of music across generations.

A celebration of being a little bit odd, finding your people and the power of music to connect us.

For Steffi, going to school everyday is an exercise in survival. She's never fit in with any of the groups at school, and she's viciously teased by the other girls in her class. The only way she escapes is through her music especially jazz music.

When Steffi hears her favourite jazz song playing through an open window of a retirement home on her walk home from school, she decides to go in and introduce herself. The old man playing her favorite song is Alvar. When Alvar was a teenager in World War II Sweden, he dreamed of being in a real jazz band. Then and now, Alvar's escape is music especially jazz music.

Through their unconventional friendship, Steffi comes to realise that she won't always feel alone. She can go to music school in Stockholm. She can be a real musician. She can be a jitterbug, just like Alvar.

But how can Steffi convince her parents to let her go to Stockholm to audition? And how is it that Steffi's school, the retirement home, the music and even Steffi's worst bully are somehow all connected to Alvar? Can it be that the people least like us are the ones we need to help us tell our own stories?
