All I want for Christmas is ... a new GEEK GIRL story! Harriet Manners knows a lot about Christmas. She knows that every year Santa climbs down 91.8 million chimneys. She knows that Rudolph the red-nosed reindeer was almost definitely a girl. She knows that the first artificial Christmas trees were made out of goose feathers. But this Christmas is extra special for Harriet, because four days ago she had her First Ever Kiss. Now she just needs to work out what's supposed to happen next. A romantic festive treat from the internationally bestselling award-winning author of the GEEK GIRL series.
