The Longest Trip Home is John Grogan's second memoir (following Marley and Me). He tells of growing up outside Detroit, part of happy family whose parents were defined by their devout Catholicism. As he grew up, he found himself less accepting of their faith, eventually making his break from their religion. As he moved into adulthood and away from their influence, his relationship with them became strained. As they became older and his father's health began deteriorating, he needed to make his trip home.
The Longest Trip Home has received mostly positive reviews with the Rocky Mountain News saying, "Grogan is no lightweight. This is a serious story of how he painfully redefines his relationship with his parents and copes with their aging. But best of all, his stories of their unconditional love despite his abundant youthful mischief will evoke all the best parts of your childhood."
