["Cecily"] is too slight to be a novel. The time span is short, the three dimensional characters few, the action limited, and little is finally resolved. What there is, however, is tightly knit and plausible, the characters of Tim, Elizabeth and Cecily clearly enough drawn so that Cecily's catalytic effect on an otherwise emotionally well-balanced Elizabeth is quite believable. It is well done, but slight.
