The whole book is sort of about the quickly reversible life. Having fun, getting a job, going out a lot, not making a lot decisions. It's all sort of disposable. I guess that's why he called it Boomtown. I'm a little slow on the uptake. Everyone rides the wave and then moves on.
Read this a while ago, likely soon after it was published. Well written. Good characters. Compelling depiction of the dot com bubble from inside it, though heavily fictionalized. I liked the realistic illustrations of the types of young people in Manhattan at the time. The main character finds his inner writer, which is always a bit hollow for me. Finding one's self through writing is a disappointingly obvious discovery for the main character of a somewhat literary novel.
