Irene by Tracy St. John

She searched for freedom and found a Kalquorian clan.

Irene Jonson is a rising star in opera, thanks to Earth forcing her to leave her parents as a teen to join a prestigious opera company. Years later, she loves music, but she wants the freedom to forge her own path as a performer and be reunited with her family.
Sherv, Rusp, and Jemi are a clan and band playing hard, driving music. Success means more than fame and fortune; it would show their disapproving families they’ve chosen the lives they were meant to live. Encountering Irene, creating a new and exciting sound, gives them that opportunity…and a chance at love.
Two worlds on the brink of war threaten everything Irene and Clan Sherv have built and everything they dream of. Two worlds are bent on snatching Irene from the men and music she loves. What chance do four misfit musicians possibly have against Earth and the Kalquorian Empire?
