I suppose it's about being sisters, being part of family, importance of trusting your instinct. Have to say I didn't enjoy it as much as her other books. Gillian was getting away with murder and instead of acknowledging it, Hoffman gave her other way out. Gillian was a no good, annoying, irresponsible woman, then she received without any effort, the love a good man and afterwards dignified life. I don't begrudge Sally her happiness, she earned every cent of it but I think Hoffman was babying Gillian, her life is indeed a result of magic.
