Juniper Lemon's Happiness Index

It''s hard to keep close a person everyone keeps telling you is gone.
It''s been sixty-five days since the accident that ripped Juniper''s world apart. Life without her kind, beautiful, vibrant big sister Camilla is a colder, darker place.
Until she discovers the letter. The letter Camie wrote, but never got to send. It''s mysteriously addressed to ''You'' and dated July 4th - the day of the accident. Desperate to learn the identity of Camie''s secret love, Juniper starts to investigate.
But then she loses something herself. A card from her daily ritual, The Happiness Index: little notecards on which she rates the day. The Index has been holding Juniper together since Camie''s death - but without this card, there''s a hole. And this particular card contains Juniper''s own secret: a memory she can''t let anyone else find out.
An unforgettable story of love, loss, mistakes and memories.
