Statutes of Limitations by VaccaD

Question 9

There should be a statute of limitation on grief. A rulebook that says it is all right to wake up crying, but only for a month. That after 42 days you will no longer turn with your heart racing, certain you have heard her call out your name.

The quote above is from My Sister's Keeper, a novel by WHAT AUTHOR whose other works include A Change of Heart and Nineteen Minutes?
