A fun-filled adventure celebrating friendship and the great outdoors, from a Carnegie Medal-winning author. It's Art Week and Lara's class is off for a week's adventure in a big house in the middle of the woods. Mr Mac is keen to catch every moment on film - even the coach turning up and Mrs Bikila racing to catch it. Everyone gets stuck in to a big art project but when Lara's friend Ted lets her into a project of his own - a magical treehouse high up in the branches - the race is on to keep it secret as long as possible.
