Short review: This is a short book (only 160 pages) but I think it does more to describe a right understanding of Christian sexuality than most marriage and sex books I have read.
The first half of the book is biographical, describing how Hill became aware of his sexual orientation and then how he came to the place of understanding celibacy as the only option for him. I think the description of the struggle is important to his understanding. Many do not come to the same place, but I think he clearly describes how he came to the position.
The second half walks through brief bios of two other celibate Christians and attempts to ground his understanding in something more than his 20 something experience.
I think this is a good book both to understand one person's view of homosexuality and the issues it raises as a Christian, but also a takes a different look at the purpose and meaning of sexuality as Christians. As someone committed to abstaining from sex, Hill brings some fresh eyes.
