Query: Fantastic read

I bought this for my book club, not knowing what to expect. I absolutely loved it and couldn't put it down! The rest of my club liked it, too. None of us found anything about it we disliked, and our discussion of it ran almost twice as long as normal. I especially loved the twist in the plot ...I had to go reread some parts to see where my mind had tricked me and how Gruen had written the double meaning so it didn't sound ambiguous at all during the first read. Quality writing.
