Tara is pretty, popular, and smart. She has friends and a family who love her. But everytime she walks to school, she has to count all the cracks on the sidewalk. And if she loses count, she has to run back home and start again. And then she has to order her food perfectly. And pray everytime someone swears. And confess every sin she's even thought of. And kiss doorknobs. All of this confuses and humiliates Tara as she and her family try to figure out what is wrong with her.
This somewhat autobiographic and gruelling realistic portrayal of obsessive-compulsive disorder covers ground that Tashjian went at in Multiple Choice which I reviewed a month or two ago. Kissing Doorknobs is a less poetic read, but probably a better portrayal of the disease. Hesser has a somewhat clunky style (a bit reminescent of Judy Blume actually), but the writing is not bad. And her story makes up for it.
This is a good book if you're looking to understand OCD better, not such a good book for entertainment however.
