This is a moving, poignant story that explores family relationships and the devastation that is caused by both dementia and the perceptions people have of it.
Cavanagh has crafted a novel around the main character's need for understanding from his son even as he searches his soul for ways to understand his own late father, a man who disappeared before his time as a victim of early-onset Alzheimer's disease. Urgency is added to the situation as his protagonist starts to suspect that he may also be a victim of the hereditary disease's insidious progress. Even as he fears telling his son about the possibility that both of them may one day succumb to the affliction, a new crisis emerges to give him a last chance to save his family--or lose it all forever.
The novel is well-written (in a simple, direct style) and enjoyable, and I found the protagonist, Dean, easy to relate to and understand. His journey to retrace the "missing steps" of his life, both by himself and with those around him is worth taking and many readers will likely find parallels with their own lives and family stories.
