Skillfully crafted but no spark, no heart. The author mathematically avoids saying anything (2/3 sisters need to come home, 1/3 sisters needs to leave, 2/3 sisters need men, 1/3 needs to stop relying on men, ect). The result is a book that is an A+ exercise in setting up problems based on well-defined characters, and working through their problems to a cheerful finish. But it feels like an exercise, not an adventure. Conflict is present, but tepid. The only thing that makes these characters special is growing up in a house where the father loves Shakespeare. Not enough spark to sustain a whole novel.
