Rolling thunder
(Book)

Lieutenant Patricia Kelly Elizabeth Strickland--otherwise known as Podkayne--is a third-generation Martian. Her grandfather, Manny, was one of the first men to set foot on Mars. So Poddy has some planet-sized shoes to fill. That's why she's joined the Music, Arts, and Drama Division of the Martian Navy. Though some may say her voice is a weapon in itself, Poddy passed the audition. And now she's going to Europa, one of Jupiter's many moons, to be an entertainer. But she's about to learn that there's plenty of danger to go around in the Martian Navy, even if you've just signed on to sing.
