The Hatmakers

Cordelia comes from a long line of magical milliners, who weave alchemy and enchantment into every hat. In Cordelia's world, Making—crafting items such as hats, cloaks, watches, boots and gloves from magical ingredients—is a rare and ancient skill, and only a few special Maker families remain.

Ever since Cordelia discovered the hidden map in her father's precious telescope, she's been searching the streets of London by starlight and trying to uncover its secrets. She's sure that her missing father is out there somewhere and that if she follows his map, she'll finally discover the truth about his disappearance. She never expects to stumble upon a secret society of mapmakers - or to learn that magic isn't limited to the few maker families, but is instead is all around, if you just know where to look.

Cordelia Hatmaker has finally united the Maker families and restored the kingdom's trust in Maker magic. But mysterious outbreaks of chaotic magic are beginning to happen across London. And then the unthinkable happens...Cordelia is accused of treason. As the guards close in, she must flee London at once. With her father, Prospero, and friends, Sam and Goose, Cordelia sets sail on her family's ship, Little Bear, for the adventure of a lifetime.

Gwyn has never wanted to act like a lady. She much prefers fighting with her wooden sword to weaving intricate tapestries. When her father takes her to join the royal court at Tintagel, Gwyn meets Merlin: a wild young boy with unique powers, in desperate need of her help. They flee Tintagel together, and before long, the young prince, Arthur, joins them. So begins an epic journey across ancient Britain, involving giants, mermaids, unicorns and witches - and their discovery of a truly monstrous plan.
