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 whisks readers away on a fantastical adventure where anything is possible, before returning to what matters most: friendship. With a glorious double lift-the-flap spread, this joyful picture book celebrates the transformative power of creativity and the fun you can have with your best friend right beside you.
