Killing November by Adriana Mather
What it's about : November Adley sees the end to her sheltered life in a quiet New England town when her widowed father abruptly informs her that she needs to leave her home. He's sending her to an exclusive boarding school for her protection while he deals with threats against their family. But this isn't a traditional boarding school. She finds herself in an isolated castle. There is no electricity and no means of communicating with the outside world, and the students are a bit odd, to say the least. They happen to be the children of elite strategists who have been maneuvering and influencing the world for thousands of years. Instead of mathematics and literature, students at the Academy Absconditi learn how to wield weapons, both physical and psychological, and history is taught. Still, only so they might manipulate the future.
Why you might like it : Anything is possible in this world of cloaks and daggers. I found this to be an entertaining read, the mystery and action take the focus, but there is a little romance that helps lighten up an intense plot. Between the boarding-school setting, the lessons in espionage, and the murder mystery, there's plenty to grab readers, and leaves the door open for sequels.
