Here are the ones we've already read, along with my ratings:
Feb: Prey Michael Crichton (Jeremy's pick) A
Feb-Mar: Terminal Man Michale Crichton (Jeremy's pick) A-
Mar-Apr: The Omnivore's Dilemma Young Reader's Edition Michael Pollan (my pick) A
Apr-May: Jurassic Park Michael Crichton (Jeremy's pick) A
I'm enjoying this thoroughly; I'd like to keep an ongoing tally and see how far we can get. :)
