'Andy Shepherd is an utter treasure. Magic grows wherever she writes and this is another warm, witty and wondrous adventure' - Maz Evans, author of WHO LET THE GODS OUT?

You won't believe what nature gets up to when you pay attention!

When Iggy and his brother Cal move to the countryside, they can't wait to get exploring. Greenacre certainly isn't an ordinary house. The plants grow in the blink of an eye, the little wooden animals dotted about the rooms never stay where they are put, and Iggy can't help but feel that the trees outside are beckoning him towards the overgrown wood at the bottom of the garden.

Some say that Wildtop Wood is dangerous; some say it's a place full of wonder. Iggy, Cal and their new friend Mae decide that the only way to find out which is to venture into the woods themselves - where they discover something that desperately needs their help. What is the secret that lies at the heart of the trees - and will Iggy, Cal and Mae be able to summon the wild green magic needed to reveal it?
