Here's the summary from the catalog:
Two teens discover the true danger of love in this gripping novel from Printz Honor–winning author Chris Lynch.
Oliver loves Junie Blue. That’s true. Pretty much everything else is a lie. Both known for their deceit, Junie and O’s relationship was the only honest thing they had. But now that’s over. Oliver’s been dumped, and he’s miserable. Junie says they’re done. Unless she’s lying?
Junie’s father works for One Who Knows, the head of an organized crime family. He won’t tell O where Junie is, not even after O hears a rumor that Junie’s won the lottery—and that One Who Knows expects to be given her ticket. O fears Junie’s in danger, and he’s determined to come to her rescue. But is there honestly anything he can do?
