This week, my WoW pick is: The Book of Spells by Kate Brian (publication date 21 December 2010).

Just as the Private series comes to a close, we take a look back. Hundred years ago, the originals Billings School for Girls and was the sister school to Easton Academy. Meant to turn girls into dutiful wives, it ended up producing one of the school's most enduring legacies.
At the helm is Elizabeth Williams. Joining with her friends, they decide to form the Billings Literary Society. Initiation is difficult and dangerous, but once the eleven girls are part of the society, she informs them she would like them to a part of her coven. A powerful witch by birth, Elizabeth shares the book of spells that has been passed through her family. The girls cast charms, cursing the headmaster and giving blisters to boys with wandering hands.
But soon things grow sinister and the coven begins to splinter, with some wanting eternal wealth and others looking for even darker magic. Can Elizabeth put a stop to what she has created? And what repercussions will this have for the future girls of Billings?
