This secret is killing me.

It's only one line from her fifteen-year-old daughter's diary, but Susan knows it means everything. Charlotte is smart, popular, and beautiful. She is also in a coma following what looks like a desperate suicide attempt. What's more, Susan has no idea what compelled her daughter to step out in front of a city bus.

Did she really know her daughter at all? In her hunt for the truth, Susan begins to mistrust everyone close to Charlotte, and she's forced to look further, into the depths of her own past. The secrets hidden there may destroy them both.
