Jimi & Me by Jaime Adoff

Keith's beloved father is killed in a robbery and the 13-year-old's world falls apart.  Without the life insurance they expected, his music producer father's death leaves Keith and his mom destitute.  Moving from a nice apartment in New York to his aunt's small Ohio town where a biracial kid does not find easy acceptance.  There he challenges his new school by dressing like Jimi Hendrix, the musical hero shared with his father.   When his mom discovers the reason his dad left them with nothing, Keith vows to meet the secret son his father seems to have cherished more than him.
