Tom Fletcher says: ‘As many people know Christmas and dinosaurs are two of my favourite things and so I couldn’t resist returning to the world of the Christmasaurus with not one but two books this year! I have popped my Christmas tree back up and am excited to share that I have written a third book in my CHRISTMASAURUS middle grade series.It’s been a lot of fun to step back into the festive world and go on a brand new journey with a very special boy and a very special dinosaur in THE CHRISTMASAURUS AND THE NAUGHTY LIST. But that’s not all, I am also over the moon to be able to introduce younger readers to the Christmasaurus and have magically adapted the first story into a rhyming and read aloud picture book, THE CHRISTMASAURUS (PICTURE BOOK), which has been illustrated by the incredibly talented Shane Devries. Christmas can’t come soon enough!’
