Will a festive winter solstice party cure the dinosaurs of their midwinter blues? A Gigantosaurus adventure in paperback, with bonus stickers.

It’s the shortest day of the year, and Mazu, Tiny, Rocky, and Bill are feeling awfully gloomy. When the sun rises so late and sets so early, there’s barely enough daylight to do anything, let alone something fun. So when Tiny decides to cheer everyone up with an extravagant holiday party, all of the dinosaurs in Cretacea are excited-and Tiny even invites the fearsome Giganto. But a last-minute bash is tough to pull off, and pretty soon everything from the decorations to the presents has gone wrong. Can Tiny salvage it all and throw the holiday party she promised?
