I cannot remember what it's called, and it's driving me crazy! this is what i remember from the plot. this girl's parents left her, and she wants to go visit their grave after a really long time. her friends go with her, and the whole story is kind of their road trip. she's really big on coincidences, and knows a lot of them. when they get to the parents' place, the other kids find out that the parents "leaving her" was actually them dying in a plane explosion when she was younger. she visited her old house, and then their grave.
