Ella is ten, and loves inventing new things. Leo is three, and loves playing with his big sister. But sometimes Ella gets mad at Leo, especially when he keeps getting in the way of Ella's inventions. And when Ella invents a time machine, Leo is accidentally transported back to the age of the dinosaurs. Ella manages to save him, but Leo brings a dinosaur egg back to the present with him. The egg hatches, and Ella must find a way to save not only Leo, but the whole world.

Howl with laughter with the THIRD book in the hilarious full-colour, illustrated series, Dog Man, from the creator of Captain Underpants! He was the best of dogs... He was the worst of dogs... It was the age of invention... It was the season of surprise... It was the eve of supa sadness... It was the dawn of hope... Dog Man hasn't always been a paws-itive addition to the police force. While he can muzzle miscreants, he tends to leave a slick of slobber in his wake! This time, Petey the cat's dragged in a tiny bit of trouble -- a double in the form of a super-cute kitten. Dog Man will have to work twice as hard to bust these furballs and remain top dog! Dav Pilkey's wildly popular Dog Man series appeals to readers of all ages and explores universally positive themes, including: empathy, kindness, persistence, and the importance of being true to one's self. Full colour pages throughout.
