Estranged Heart by Ashlynn Mills

Side effects they don’t list with a heart transplant: Lusting after a man you’ve never met before.
On the verge of losing my life, I’m doing my best to accept my fate. Then I receive a message from the hospital. A second chance, an organ donor. A man who has a zero chance of waking up from a bad car crash turns out to be the perfect match.
I’ll get to live the life he lost.
My wife thinks it’s a miracle, a dream come true. She wants me as much as the day we first met, but it’s no longer her face I see when I close my eyes at night.
To me, it feels like we’re strangers playing house. Her touch isn’t the same as it once was, and the only person my body aches for is someone I normally would never go for.
I don’t know him, but my dreams, thoughts, and heart do. Somehow, I’m being led to every place he’s been. Places that feel like ones we’ve been to together. It’s impossible, I know, but also the only thing that makes sense.
It might have been his husband who brought us together but he’s the reason I keep coming back. Too bad me being straight and married aren’t the only obstacles getting in my way of staying.
