A golden retriever stars in this memoir, Until Tuesday. Luis’s memoir is about his experiences as an Iraq veteran who returns to New York recovering from injuries with a severe case of post-traumatic stress disorder. Failing to cope with a “new”world and at the end of his sanity, Luis enlists the help of a service dog to help him re-acclimate. It is a charming story of the bond that grows between Luis and Tuesday. More than that, it is a dramatic look into the mind of a person suffering from PTSD. Montalvan, a former captain in the US Army, is most compelling when he zones in on how he reacts to his world. He is an advocate for service dogs to help the disabled.
