I wasn't sure about this book when I picked it up, it's been a while since I read a western, especially one meant for young adults. But I was surprised how much I enjoyed it, especially how into the rodeo descriptions I got considering I'm not a rodeo fan. This book was exciting and moving.
Spoilers ahead
Will and Denny are 15-year-old twin brothers living on a ranch in rural Colorado in 1940. Denny has Downs Syndrome (it's described but never outright named in the narrative) and since their mother died, Will has become the main caretaker for his brother. Will loves his brother, but resents that his role in life has been chosen for him. His father doesn't recognize his cowboying talents and doesn't treat him like a man. Will sees a dead-end future, just taking care of Denny forever and never being recognized or seeing any more of the world. Denny is sweet and adores Will, he is too sensitive to let Will kill the coyote that killed their dog. Denny is easily scared and relies on his brother. The "small white scar" refers to identical cuts they have on their index finger from when they were 6, they press their fingers together as a sign that they are brothers forever. When Will's father changes his plans and needs to move part of the herd because of the drought that has hit their land, he tells Will that he can't go to the rodeo Will was planning on competing in. Will is outraged, that rodeo was going to be his ticket out - he was going to win it and then not come home, taking on work at one of the ranches that would be sure to want him. So he decides to run away and go anyway, the problem is that Denny follows him and won't go home. There are several dangerous circumstances that make it so he can't go, and he's getting sick from a rattle snake bite, so Will has to take him with him. They get to La Junta and Will gets him taken care of by the town doctor - their father's friend. They find out that their father will be there the next day - the day of the rodeo, but Will is still determined to compete and start his own life his way.
I thought this book did a decent job depicting someone with a disability in a way that was balanced and accurate. Through Will's perspective you could see how caring for his brother could be considered a burden and frustrating at times. Will was always having to stop or change what he was doing out of consideration for Denny. The town doctor is amazed at the progress that Denny has made, he is highly intelligent, capable, and able to follow conversation for someone with his condition (considering how much was known about it then). In fact, the dr reveals that when they were born, he advised their parents to institutionalize Denny immediately - this was common practice then, especially because of the shortened life span of people with his form of "feeblemindedness." The doctor credits Will with Denny's ability and asks how he did it, to which Will replies, "He's my brother." Will does well in the rodeo, winning 3 events, but it knocked out by the bull after a successful ride. He ties for the grandprize, but because of his concussion loses the rope off. He still wins a significant amount of $ as well as respect and a job offer from a rancher. But it's then that he realizes how much he loves his ranch. His dad comes and apologizes that he hasn't been willing to recognize that Will is a man now, and that he pulled away after their mother died and left the rearing of Denny to Will. He promises that he'll treat Will as a man and a good rancher if he'll come home and if Will isn't satisfied, he'll let him go to another ranch. Meanwhile, Doc Sidders offers to let Denny stay with him and have him help out. Denny is happy with that and excited that he too gets to be a man and make his own decisions. It ends on a hopeful note, with Will going home and recognizing the things that Denny has taught him, that he's the person he is because of the sweetness and difficulty of his twin brother. "The same blood runs through" them both and he's finally not afraid of that.
