Kill Switch by Chris Lynch is story with many themes: it is a quest to find a safe place for Daniel Cameron's grandpa, Da, who is losing his mind to Alzheimer's and becoming increasingly unpredictable; a loyalty test for Daniel as he struggles to understand why Da's former employers from the Department of Agriculture are tracking them; and a labor of love to keep Da focused on the present. It is easy to get caught up in Daniel's dilemmas, but increasingly troubling to see the consequences of the choices that Daniel feels he is forced to make. Newly graduated from high school, Daniel takes on the full time job of caring for his grandfather, determined to enjoy their remaining time together before he must leave for college. Listening to Da's rants, Daniel starts to suspect that Da's past was not simply one of a paper-pushing government bureaucrat. It also seems obvious that former co-workers are concerned about Da's failure to maintain secrecy about his past and want him silenced. Even Daniel's parents and sister have lost patience with Da. After Da has been put under observation to avoid prosecution for car theft, Daniel decides to take matters into his own hands. It is tragic to see the ravages that dementia wreaks on a proud individual, his family and society. Both Daniel and his grandfather are complex, challenging characters and the path they have chosen leads them into danger, violence and betrayal. Kill Switch is riveting and thought-provoking.
