Heart of Stone - May-December Hearts Collection

"Hi! I'm Dr. Dream, and I'm probably the hottest guy you'll ever meet. I have silver hair, but I'm young at heart. I have lots of fans, but I'm looking for my Number One. Is it you, younger guy? Hit me up!"ER Deputy Chief Stone Dooley got the surprise of his life when he learned his twin daughters had signed him up for a gay dating site, without his knowledge, three years after he became a widower.
What was supposed to be a quick drink and an apology for his daughters' prank, turned into tentative friendship and an agreement to swap services-Stone would take care of the younger man's ailing grandfather, if the young guy would help out with childcare for his daughters over the summer. Twists and turns test their blossoming friendship. Grief, loss, secrets, and a threat to tear his family apart all test Stone's limits to his breaking point.
What is the key to weathering the storms heading in Stone's direction? Maybe a blond-haired young man with jade green eyes could crack the Heart of Stone?This book is an age-gap MM romance. It is part of the May-December Hearts Collection, but it is a stand-alone story that ends with a happily ever after.
