Mistik Lake, by Martha Brooks
Odella's world begins to fall apart as her parents grow apart and are divorced, and as her mother subsequently dies. Trying to cope with these tragedies, and with being the older sister and necessary nurturer to her two younger sisters, Odella also finds herself needing to explore the causes of her mother's sorrows.
Not everything is bleak though. While at the family cottage on Mistik Lake, Odella meets Jimmy, an aspiring journalist, who seems to bring out the best in her, and to bring her a different kind of joy. And there is also her great aunt Gloria, a support to everyone, and a calming influence. She may hold the key to understanding the causes of Odella's family tragedies.
This is just a beautifully written, layered tapestry of a story. I couldn't put it down, and I found myself drawn into the world of the story. Definitely one of the best new teen books of the year.
