Saving Zaria

Paola was only 11 when her older sister, Zaria, was murdered. Every since Zaria died her life haven't been the same at all. Her parents seem to argue more than usual, her mother is a complete wreck, her father works even more late, her grades are becoming worst and worst. And the worst part is, is that Zaria's old boyfriend gives Paola Zaria's diary and as she explores her sister's diary she learns more about her than she ever knew before.
