Overall, I think this novel should make it on everyone's reading list. If for no other reason, readers have to find out what happened to Sal's mom, Phoebe's mom, the "lunatic", and have to find out who was leaving the letters and what happens to grams. I'm not going to spoil it for you now, though.

But, don't just take my word for it. I read this novel with Breandan, Cameron, and Myles. You could ask one of them.

“On that night after Phoebe had given her Pandora report, I thought about the Hope in Pandora's box. Maybe when everything seemed sad and miserable, Phoebe and I could both hope that something might start to go right.” (All quotes are from
