The plotting is solid, but it's the characters that make this book such a fantastic read. This is the story of adopted Saffy finding her place in her family, sure, but it's also an introduction to the nice, but nutty, Cassons. Saffy's family members are flawed but also creative and loyal, including mother Eve, who forgets things like dinner, and who is overly permissive because she believes her kids "were in every way more talented, intelligent, and wise than she would ever be."
The only character who isn't particularly sympathetic is Bill, the father, who spends his week acting the part of an artist in London, belittling his talented wife who must juggle her work and four children alone at home. But he is shot down at times by his outspoken offspring, and ultimately learns to see his wife's artistic ability. In the end, this is a funny and tender novel. Readers will fall in love with the Cassons, and be excited to get Hilary McKay's other books about the children who live and create in the unkempt Banana House.
