The Thief by Claire North
I'm not a fan of playing hide-and-seek. When I was a kid, I was always afraid everyone else would go inside or to another kid's house and just leave me hiding. I don't think it ever actually happened, but that doesn't mean I didn't worry about it. And it was even worse if it was dark.
The hide-and-seek game in The Thief is awesome though. The "board" is Thailand in the 1930s and the stakes are huge, but the game might be unfairly weighted. This is the second in the trilogy and I think they should definitely be read, or listened to, in order. Thene's game in The Serpent was not exactly fair either, but that was nothing in comparison to the disadvantages our player is dealing with here. It's a thread thoughout - the Gameshouse may not be as fair as it (she) would like you to believe.
Once again, North does wonderful job building her world. Thailand in the 30s...
