We meet Easton as his husband is dying, and he is asked the really hard question of agreeing to donating his heart to someone who is desperate for a new heart - a really tough decision for him to make even though he knew there was no chance of recovery for his husband.
River is a man who needs a new heart, and out of the blue he gets the call to say there is a heart for him, and he is overjoyed. He gets his new heart, and then resumes his life, with a few adjustments. He also finds that he is thinking differently about relationships, and wonders if his new heart is the reason for these feelings.
Easton knows the name of the person who had received his husbands heart, and asks his husbands best friend to make sure he was a good person, but he doesn't have any intention of meeting the person - until a day that he decides he just wants to see him, and somehow manages to save his life in the process!!
Easton and River become friends, which actually begins to evolve into something meaningful, but Easton keeps the secret about knowing that River has his husbands heart beating inside his chest - until one fateful day when clearing out some of his late husbands belongings from the house with Rivers help, the secret is a secret no more........
