Wizard's Daughter begins with Nicholas Vail, a newly titled earl who goes to London to seek out a specific young woman. Why he does this, he is unsure--he just knows he has to meet her. And she turns out to be Rosalind de La Fontaine, a beautiful 18-year old who has no real idea who she is. Found beaten and bloody when she was quite young, the only thing she remembered was the bit to a song.
Nicholas and Rosalind quickly marry and return to Nicholas' house, where all sorts of things begin to happen. There's a ghost living in the library. Books appear, books that only Rosalind can read. And a nagging sense that Rosalind is not her real name--and her history is tied up with mysterious tales of the Pale.
An engrossing read, although the ending was added a little too easily. The novel is long, and some of the details are confusing, but the overall story is engaging.
