A fantastical, botanical adventure about friendship, bravery - and finding home in a new place. Fern has spent her whole life in the rainforest, and loves nothing more than climbing, exploring and talking to the trees. When she suddenly has to leave all that behind and move to London, with only an eccentric uncle for company, Fern feels entirely uprooted.
But when she meets a little plant that can understand her every word, it seems that things are looking up! That is until strange things start happening in the city: giant lily pads on the Thames, monkey vines on the London Eye, and now her new friend is starting to wilt... Can they solve this growing mystery together - before it's too late?
