The thing that I liked best about the book was that it introduced sensitive issues without putting too many value judgements on them. The was especially evident with Sam's parents involvement in the church. While this attitude is shown as being hard on Sam, there is no outright condemnation of the church, and there is another minister who is portrayed sympathetically. The parents are amicable in their divorce, keeping Allie's well being first in their thoughts. The best bit of information Sam is given is that she needs to stay safe, which was critically important in 1977 when teachers could lose their jobs if the slightest inkling of homosexuality was revealed, but is still good advice to students today. Sam has an ally in her sister, but clearly would not be safe if she continued to bring the topic of her sexuality up with her parents.
The late 1970s were very different from the earlier part of the decade, and Hitchcock manages to accurately portray the social Zeitgeist while throwing in details like a boy wearing a silky shirt with sleeves rolled up and a comb in his back pocket with the handle sticking out. Yes! And I know, because, like Allie and Sam, I was a seventh grader in 1977!
One True Way is a great addition to diverse middle school collections. Add it to Barakiva's One Many Guy, Federle's Better Nate Than Ever, Sayre's Husky, Wittlinger's Saturdays with Hitchock, Gino's George, Hennessey's The Other Boy, Polonsky's Gracefully Grayson, and other books that show different experiences with sexual orientation and gender identity in a way that will make middle school readers more understanding of the challenges faced by the people in the world around them.
My only criticism-- the characters should have been named Lisa and Jenny. Or Pat. Or even Terry, if we wanted a more gender neutral name. I did know a few Allisons, but never knew any Samanthas. My own name was #5 in popularity for my age cohort!
