I loved this book i read it several times, it really dipicts parts of depression well, as well as showing the result of some of the children of the hippy generation that become so lost when there parents abandoned them. I wrote a Character analysis for school it is not very good but it gives you the basic idea:
Jo: figuring what she wants to do with the rest of her life. As a child she is left with the darker sides of her mind, as her father left her alone, when she reaches adolescence she is also lost by the abandonment of her mother, and the now lesser support of her father. She feels lost and frightened about what she might not become.
Lucy: Jo's mother leaves Jo when she is very young to deal with her father. Later takes Jo into her home when Jo is already passed 18. Marry's again to Alios, and when he dies she locks her self in her room, and creates a room full of dead flowers pollen, and later disregards Alios' existence. Has a hard time dealing with the idea that he she still has a daughter and tells everyone that it is her younger sister.
Jo's dad: not very parental, loves Jo, but has no connection with her, re-marries. A absent minded professor with his writing, even though it has never bin and never does get published
