Terribly frustrating read. Written in the same style as World War Z, about simultaneous plane crashes that mysteriously leave 3 (maybe 4 - that's supposed to be part of the intrigue) surviving children. Something's not right about the kids, though what exactly that is - along with what caused the plane crashes, not to mention any number of other critical details - is left unresolved.

Never found myself much caring about the characters, didn't enjoy the pacing (the first 2/3 of the book hints at what happened in the past, without ever actually saying what happened; when things start actually happening, it's entirely anti-climactic), and ultimately struggled to make it to the end.
