"Lake of Dead Languages" by Carol Goodman. Jane is a teacher of Latin at a school she attended as a child. This novel in fascinating as it describes the Heart Lake School for girls, and a mystery that lays beneath the lake waiting to be revealed.
I loved the novel's rich description of the lake's ice and snow and the and the childhood connections with the lake, from skating to peering out at its dangers. The book has a "Parent Trap", the movie feel to it when it describes crossing the lake in order to meet friends who are otherwise not allowed to cross the lake.
I, too, have spent childhood summers at a lake, for summer camp, and the way character of Jane describes this experience is very soothing. Jane's role as a teacher leaves her admired by many of her students. When she tells her students to keep a journal of their feelings, she is able to find secrets about her students that remind her of cult like instincts and secret pacts that she, too, kept with her own friends as a child.
