Query: Can you still be a teenager at age 30?

Rachel and Darcy are best friends. Rachel and Dexter (Darcy's fiance) wind up in bed together. The remaining 20+ chapters are devoted to Rachel's angst: Does Dex love her or Darcy? Will Dex call off the wedding? Should Rachel tell Dex that Darcy has been cheating on him? It's all very junior high school. I was never able to figure out Dexter's appeal, other than good looks and the fact that Darcy was engaged to him. Hardly the stuff of which soul mates are made. I DID read through until the end, and Giffin's sense of humor does make me smile, but this is not a novel about anything remotely approaching adult relationships.
