In seven years at Hogwarts, Nerine Black and Tom Riddle have never managed to exist in the same room without turning it into a battlefield. What began as childish cruelty in their first years-when she made his life a living hell-has long since grown into something far uglier. Now they don't simply dislike each other. They want to destroy each other. Unfortunately, hatred has an unsettling habit of looking a lot like obsession.
Throw in two of the brightest minds Hogwarts has ever seen, an endless competition for first place, professors who insist on pairing them together, and a castle that seems determined to force them into each other's orbit, and things are bound to become even more dangerous...
