Pioneering aviatrix Emmaline and her bouncy pilot, Rubberbones, are safe from the headmistresses and monsters of St. Grimelda's School for the time being. But now, a ruthless master criminal known as the Faceless Fiend wants to kidnap their haughty houseguest, Princess Purnah. With help, Emmaline and Rubberbones devise a bold, clever and completely insane escape plan — and things get worse. Readers will follow desperate chases, food fights, ridiculous costumes, balloons over London and more in this book written by Howard Whitehouse and illustrated by Bill Slavin.
