The Lake of Dead Languages by Carol Goodman

Although it was a bit predictable, I liked this thriller. It's set at a not-so-prestigious girls boarding school near the Adirondacks. The heroine, Jane, once a Latin student and now a Latin teacher, has to deal with deaths in her past that are being replayed in her present. The dark, icy atmosphere around the school's lake and the dead language provide interesting metaphors for Jane's turmoil. Goodman is a good writer and storyteller. I'll read the next one when it comes along.
