Why my literature professor thought this was a good 'first exposure to DeLillo' text is beyond me. Almost swore him off for good after this absolute slog. A shame considering how interesting the premise is! Terrorism, hostages, a reclusive writer, weird relationship dynamics...
Should I try again?

I'm with you; this one is a bit of a mess. Definitely not the best DeLillo and not a good intro either imo. Libra, Underworld, and White Noise are all excellent.
