Ginnah Howard’s first novel opens on a cold March night in upstate New York with a woman and her 37-year-old son en route to a detox facility. Del is an anxious person who would prefer not to drive, a “worry-bird,” as her son, Mark, says, “120 pounds of nervous coming at you.” In her rush to get to the hospital on time, she misses the exit to the Thruway and ends up on icy Route 5. When Mark takes over the driving, Del suddenly feels the car slide off the road, “but no impact, no impact,” and “for a few seconds they sit and are grateful.” This is the only moment Del and Mark will be at rest.
