Book excerpt: In Dos Rios, Texas, things aren't always as they seem.Alexis Garza has music in her blood. She's certain that one day, she'll be leaving the border town of Dos Rios, Texas behind for a glamorous life of singing stardom. Until then, however, she'll have to content herself with belting her heart out at voice classes, going to high school mariachi band practice, and helping out at the Graza family restaurant.Alexis's ordinary life takes a turn for the extraordinary when she meets the swoon-worthy lead singer of a rival high school's mariachi band. His singing (and his smile) make Alexis melt. There's one small problem-- this suave singer doesn't seem to know that Alexis exists. She's determined to make herself heard-- no matter what the cost.
