Query: Volleyball playing PI with wicked sense of humor

Carlotta Carlysle drives a cab, has convoluted love life and precocious little sister, but has time to take on bad guys and lead her reader on a non-stop thrill ride as she ferrets out illegal alien underworld. A real page-turner. A must-read if you like Sue Grafton's books.
