This book is an interesting look at service dogs and their companions. The book is a true telling of Fmr. Capt. Luis Carlos Montalvan's tours in Iraq, his injuries and returning to life as a disabled civilian. The story is just as much about Tuesday a golden retriever with some problems of his own. It was enlightening how service dogs are trained, work and help disabled people live more full lives.It was also a reminder of our wonderful military men & women need our support and help. No matter what your political views are this is a story worth reading.You cannot help but love Tuesday and hope Luis achieves his goals out west in the near future.
