Lisa McDonald, a computer scientist, was a responsible adult and a proud mother, just like most parents. She was also exhausted and under stress on the morning she inexplicably forgot to drop her toddler, Kenny, off at his daycare, just like most parents who forget a child in the car. Kenny slept peacefully while Lisa locked the car and walked into her office, leaving him to die a slow, heart wrenching death. The years since have been a living hell for Lisa, left to face the unimaginable tragedy that resulted from an involuntary failing of her working memory.
