The Tricky Part: One Boy's Fall from Trespass into Grace is a 2005 non-fiction book by Martin Moran.

[1] Between the age of 12 and 15, Martin Moran had a sexual relationship with Bob Doyle, a Vietnam veteran who was a counselor at a Catholic boys' camp.

The Tricky Part tells the story of the relationship and its effect on Moran, who grew up as a homosexual.

It describes Moran's sexual awakening, and how he and a chubby friend of his called George, go with Bob to get the camp ready.

Moran's desperate coming of age is described with candor and humor and sets out the paradox that what is, in nearly everyone's eyes, a seriously damaging experience, can be the very thing that gives "rise to transformation, even grace".
