Aubrey Glass has a collection of potential suicide notes just in case. And now, five years --- and five notes --- after leaving her hometown, Rachel is the one who goes and kills herself. There’s a voicemail from Aubrey’s former friend, left only days before her death, that Aubrey can’t bring herself to listen to --- and worse, a macabre memorial-turned-high-school reunion that promises the opportunity to catch up with everyone…including the man responsible for everything that went wrong between Aubrey and Rachel.
