A Harvest of Hearts — Andrea Eames

In the beloved tradition of Howl's Moving Castle, a whimsical and unforgettable story of fantastic adventure, common sense, and the power of love to overcome the greatest of obstacles . . .

Before Foss Butcher was Snagged, she thought no more of the magic-users than did anyone else in her tiny village. Sometimes gorgeous women in impossible carriages rolled into town and took bits of people's hearts. Everyone knew hearts fueled their magic. But Foss, plain, clumsy, and practical as a boot, never expected anyone would want hers.

True enough, when the only sorcerer in the kingdom stepped from his glossy carriage, he didn't intend to hook Foss. Sylvester's riot of black curls and perfectly etched cheekbones caught her eye a moment too long, that was all. Suddenly, Foss is cursed and finds herself stomping toward the grand City to keep his enchanted House, where her only friend is a talking cat and the walls themselves have moods.  

But as Foss learns the ways of magic, she realizes she's far from its only unwilling captive. Even Sylvester is hemmed in by spells and threats. It's said this sorcery protects king, country, and order for thousands. If Foss wants to free herself -- and, perhaps, Sylvester -- she'll have to confront it all . . . and uncover the blight nestled in the heart of the kingdom itself.
