The Hatmakers series by Tamzin Merchant is a magical and adventurous tale set in an enchanted, olden-day version of England. It follows Cordelia Hatmaker, a young girl from a magical Hatmaker family, who craft hats imbued with enchantments. When Cordelia’s father goes missing at sea, she sets out to uncover the truth behind his disappearance. Along the way, she discovers rivalries among the Maker families—Hatmakers, Bootmakers, Glovemakers, Watchmakers, and Cloakmakers—and uncovers a sinister plot to use Maker magic to start a war. As the series progresses, Cordelia faces new challenges, including secret societies, chaotic magical outbreaks, and the need to unite the Maker families to protect the essence of magic itself. There are three books in the series so far, The Hatmakers, The Mapmakers, and The Troublemakers. I would say that it is a 7+.
