When Colin finds a shoebox full of letters hidden in a stranger's attic, he knows he's supposed to throw them away. But Colin wants to rescue the letters, and find out what really happened to best friends Rosemary and Toby way back in the 1970s. Meanwhile, across town, Nevaeh also finds a mysterious letter. But this one reads like a confession to a crime. And Nevaeh knows her father, the "Junk King," expects her to join the rest of the family in blaming a single suspect: his business rival, Colin's mom. Even as one set of letters bring Colin and Nevaeh together, the one Nevaeh found threatens to tear them apart.
