Started reading Cathy's Book by Sean Stewart today, after having picked it up at MLA two weeks ago. It's a so-so YA mystery/thriller at heart, but is noteworthy for being the basis of an alternate reality game.
I'm not entirely sure what the best way to read it is, whether to read the book portion straight through before tackling the interactive features, or if I should attempt to do both things at once. One of the key features appears to be the voice mail of the protagonist (the phone number is on the cover), but I need the passkey to unlock it, which has so far eluded me. So at this point I'm inclined toward reading the book, taking lots of notes, and then playing through the game.
