Red, Red Dragon / Lynne Reid Banks

From a multi-million-copy-selling author whose work spans seven decades comes a humorous and warm-hearted story about a family of dragons in a world where humans have always been a myth ... until now.
Red is a rare red dragon who lives with his Mag and Dag in a world where dragons and Uprights are sworn enemies. Then Red meets his first Upright, a girl called Lou, who is nothing like he had imagined: she's smart, and funny ... and kind! As the pair become friends, Red learns that not only can the two species live in harmony – but maybe it's his destiny to bring them back together.
