Lenobia's Vow - P.C. Cast, Kristin Cast Wow, this was extremely sad. What's with the author and giving all of these teachers such horrendous pasts? I actually was fearful for Lenobia for a majority of this book. The Bishop made an excellent villain - evil, terrifying, not one ounce of good in him. Oh but how I loved Martin and am now intrigued about this "vow" and how it will fit in with where the series is going.
