On a summer night in 2009, three lives intersected in one American neighborhood. Two people newly in love—Teresa Butz and Jennifer Hopper, who spent many years trying to find themselves and who eventually found each other—and a young man on a dangerous psychological descent: Isaiah Kalebu, age twenty-three, the son of a distant, authoritarian father and a mother with a family history of mental illness. All three paths forever altered by a violent crime, all three stories a wake-up call to the system that failed to see the signs.
