From the publisher:
It’s getting hotter and hotter in Moominvalley, and all the creatures have taken note of the troubling weather. After a mysterious cloud appears in the sky one day, an exodus begins. The Hattifatteners, the Nibling, Mrs. Fillyjonk (and all her children), and even Mymble pack up to leave the valley. When they realize the mysterious cloud is a comet headed straight for Moominhouse, Moomin, Little My, and Snorkmaiden decide to depart their home too. As the clock ticks down, and the comet nears Moominvalley, the plot thickens. Between a tidal wave and a comet-struck Moomin, the end does seem nigh, but the day may yet be saved.
Tove Jansson’s flawless cartooning is brought to life in a whole new way within these pages. A delight for the whole family!
