Oona and her brother Fred are still coping with the death of their father from cancer a few years ago when their cat, Zook (short for zucchini) starts to have problems with kidney failure. In order to help Fred, Oona starts to tell him stories about the different lives the cat has had, just like their father used to tell stories to them. The two are also dealing with the fact that their mother is dating a man they don't like. Dylan is a male nurse, and ends up being very helpful in dealing with Zook's treatment, and Oona and Fred get a lot of support from their close-knit, multicultural Californian neighborhood. Unfortunately, Zook is not going to make it, and the family has to put the cat down. Oona deals with many problems surrounding how she got Zook (she lies quite a bit), problems with friends who become estranged, and with her mother moving on after her father's death.
This was a very compelling book, even though I knew that Zook would not have a happy ending. Readers of Rocklin's first book, One Day and One Amazing Morning on Orange Street will enjoy this story as well.
