The Miraculous Sweetmakers

It's winter, 1683, and the Great Frost has swept into London. By day, thirteen-year-old Thomasina and her friend Anne peddle sweets on the frozen river, hearing rumors of the magical Frost Fair that awakens there at night. They say if you can find it, Father Winter himself will grant any wish you have. And Thomasina has an impossible wish: the return of her twin brother, whose death left her family fractured. But once they discover Father Winter’s icy kingdom, Thomasina and Anne quickly realize the Frost Fair isn’t exactly what it seems… and that some wishes never come for free.

After facing down Father Winter and escaping the Frost Fair, Thomasina and Anne have achieved their dream. Without needing any wishes at all, they’re running their own sweetshop. But magical creatures and otherworldly beings aren’t quite done with them yet, and they soon find their friend Henry kidnapped by an evil Sea Queen and dragged down into the depths of the River Thames. Determined to save him, the girls venture into the deep and discover the enchanting world of the Free Waters.

Several months after the Frost Fair cast its spell over London, best friends Thomasina and Anne are running their own sweet shop – and, truth be told, longing for adventure again. Then the rumours begin – rumours of unexplained storms and catastrophic shipwrecks. And then disaster strikes, and their beloved friend Henry disappears: snatched by a mysterious creature, and dragged down into the depths of the River Thames. Determined to save him, the girls venture into the deep, and discover the enchanting world of the Free Waters: a vast, glittering underwater city, home to mermaids and sirens.
