One little girl wants to build a magnificent, make-believe world for her and her best friend Tilly to explore, full of fire-breathing dragons, snorkelling elephants and intergalactic rollercoasters. But as her dream world becomes bigger and bigger, poor Tilly is pushed entirely out of the picture! Join the two as they rediscover the simple joy of playing together and realise that friendship is the most magical gift of all. Fuelled by a child's limitless imagination, Iris Samartzi's playful tale takes readers on a fantastical adventure where anything is possible, before returning to what matters most - friendship.
