From Good Reads:

In the basement of a small evangelical church in southeastern Idaho, a group of young missionaries is preparing to go to the Middle East. One of them - a young man who has recently lost his father - has bought a one-way ticket. But his plans are complicated when his estranged sister returns home and makes it her mission to keep him there.

The Harvest includes heavy emotional content about the effects of family trauma, grief, death and dying, poverty, sexual identity, race, seeking a meaningful life, and how those intersect with organized evangelical Christianity.
