Joe O'Brien is an officer for the Boston Police Department, husband to Rosie, and father to four offspring when he finds out the most devastating news of his life. He's gene positive for Huntington's Disease. After a few too many mishaps, sporadic movements, and out of character rampages, he is convinced by his wife to seek help. Joe becomes someone who is unable to control his movements, thinking, and behavior. His cognitive and motor skills will continue to decline until his untimely death. What's worse is that there is a 50% chance of passing this along to his children, and the children struggle with whether they want to take the test to find out. Inside the O'Briens explore how one Irish Catholic family tries to hold it all together while things seemingly fall apart. I loved reading about this family.
