Born Wicked (The Cahill Witch Chronicles #1), by Jessica Spotswood
Release Date: February 7th, 2012
Cate Cahill and her sisters are considered eccentric bluestockings—a little odd, a little unfashionable, and far too educated for their own good. The truth is more complicated; they’re witches. And if their secret is discovered by the priests of the Brotherhood, it could mean an asylum, a prison ship—or an early grave. Before their mother died, she entrusted Cate with keeping them safe and keeping everyone, including their father, in the dark about their powers. When her father employs a governess and Cate begins to receive notes from her missing, presumed-mad godmother, her task becomes much more difficult. As Cate searches for answers in banned books and rebellious new friends, she must juggle unwanted proposals, tea parties, and an illicit attraction to the new gardener. Cate will do anything to protect her sisters, but at what cost to herself?
I know this one is not coming out any time soon, but let's face it, I could never resist a witch story.
