'Dreamer.' Mum called her. 'Always miles away.' Sadie lives by the Thames at Greenwich and longs for sea adventure. She happily whiles away hours at The Maritime Museum or gazing at The Cutty Sark and fills her head with dreams of ocean voyages on ancient sailing ships. 'And there inside she found a different world Where rigging sang and white winged sails unfurled.' One day she falls asleep beneath a cabinet in the museum and wakes to find herself embarking on an adventure she could only have dreamed of ... Duffy's lyrical poetry and Joice's richly imaginative illustrations combine to create an unforgettable voyage into a magical world of dolphins, mermaids, pirates and treasure.
