by Rebecca Stead
Random House, 2012
When seventh grader Georges (the S
is silent) moves into a Brooklyn apartment building, he meets Safer, a
twelve-year-old coffee-drinking loner and self-appointed spy. Georges
becomes Safer's first spy recruit. His assignment? Tracking the
mysterious Mr. X, who lives in the apartment upstairs. But as Safer
becomes more demanding, Georges starts to wonder: how far is too far to
go for your only friend?
