This series by Ann Brashares starts out very strong and falls off a cliff in the last book. The first two are well-realized, strongly plotted explorations of adolescence from various viewpoints. The last is inexplicable and maddening. Brashares seemed, like Alcott, tempted to have an earthquake swallow the girls so she might be finished with them and move on. I'll be interested to read her next book, now that she's put away the pants.
