There isn't much drama in Olive Town. The highlight of Cissy Sissney's days are the letters from her old schoolteacher, Miss Loucien, describing her adventures on board an old showboat with the Bright Lights Theatre Company. If only life were full of such adventure for Cissy too. But then diphtheria breaks out in Olive town, a silo crushes Cissy's home and Miss May March agrees to take Cissy and classmates, Kookie and Tibbie, to stay with Miss Loucien until Olive town is safe again. The ramshackle crew on board the Sunshine Queen sail along the 'shoals and shimmer of the Numchuck River,' performing plays for the towns scattered along the shore. Cissy and her friends have a whole host of adventures beating hustlers at their own game, catching criminals, and embarking on a daring rescue mission. They must use all their wits to survive. As their journey along the river comes to an end, Cissy must put in one last performance and this time the stakes are higher than mere applause. The award-winning author, Geraldine McCaughrean, captures the spirit of adventure and the power of imagination in this rip-roaring read.
