Hollywood Heir by Ruth Cardello

Sage Revere follows her instincts, which have led to an oddball career as a plant psychologist. As a side project, she also helps strangers find happiness. Sage has a gift for knowing who needs her help, and the brooding hunk of a loner she meets in a coffee shop certainly fits the bill. She can feel it.
On-screen, Eric Westerly is the hottest superhero there is. Offscreen, he’s out of rehab; incognito in London; and reevaluating his life, his career, and his broken family ties. All he wants is to be alone. Then along comes some daft plant whisperer who gets under his skin. She’s also sweet, sexy, and irresistible. But what’ll happen when she finds out who he is—that underneath the gray spandex, he’s just a regular guy with a Batcave?

But Eric isn’t the only one with a few secrets. And when the masks come off, Sage and Eric are going to have to trust each other if they want a Hollywood happy ending.
