I wanted to love this book, and fully expected to. Tucson, running, Boston Marathon, mostly 4 star+ reviews? How could I not? But I didn't. The book is two parallel stories. First, Billy Ball, a high schooler who experiences a humiliating event when he loses his shorts in a race and then has to deal with all the repercussions that follow. Second, his great-grandfather in the Depression years, who ran in a very early Boston Marathon but had an unfortunate experience that changed the course of his life. The overall story wasn't bad, and the writing was entertaining. But I found myself getting very bored in large sections of the book. Nothing much happened in all the boring years between the events that started both stories and their conclusions. And at the end of the book, I was unable to suspend my disbelief sufficiently to enjoy the conclusion. First, there is NO WAY that an unknown kid without coaches could win the Boston Marathon. No way. Not with the elite fields they have today. Second, the likelihood of same kid losing his shorts twice in different races and having to run naked to the finish line is infinitesimal. I actually finished the book annoyed by these two things. That having been said, the vast majority of readers loved this book, so maybe it's just me.
