Aza is subject to compulsive thoughts, so much so that at times she doesn’t feel in control of herself. Her obsessions center around the microbes in the human body.
Aza’s friend Daisy is a real firecracker who blogs romantic stories about Star Wars characters. She sets off the action in the novel by suggesting that she and Aza investigate the disappearance of Russell Pickett, a corporate CEO who is under investigation. The authorities are offering a reward of $100K for information leading to his discovery, and Daisy thinks they have an in because of Aza’s former friendship with Davis, his son.
Aza reluctantly goes along with Daisy’s idea to contact Davis but finds things complicated. Davis is glad their neglectful father is gone, but his little brother is suffering. To make matters worse, Aza is attracted to Davis, who knows very well the reason the two girls came calling.
Green seems to specialize in bitter-sweet, and this novel is no exception. It is very entertaining and ultimately touching. Aza’s problems are handled with understanding and delicacy. (It seems that Green also suffers from obsessive-compulsive disorder.) This is another winner for John Green.
