Told with extraordinary vulnerability, grace, humor, and profound insight, On Pluto is an intimate look inside the mind of Greg O’Brien, a journalist diagnosed with early- onset Alzheimer’s. But the real gem of On Pluto lies in its un(inching look inside Greg’s heart. If you’re trying to understand what it feels like to live with Alzheimer’s, and you are because you’re reading these words, then you need to read this book.” -- Lisa Genova, New York Times best-selling author of "Still Alice."
