Central Park Paradise by Kari Trumbo

Claire is approaching forty. Has love passed her by?

She’s developed an aquatic therapy to help cancer patients, if only the local oncologist believed in her. Without his support, she can’t attract people to her class, but he’s not wholly invested.
Dr. Mark Evans has devoted his life to his patients.
He’s tried to be the man his father never was, a doctor with a heart. But is he being honest with himself? Is he willing to work with Claire, even if he doesn’t believe in her treatment, to give his patients something extra?
When Claire and Mark find out the truth, it could shatter the trust they’ve built. Only honesty can treat the illness of deceit, in both of them.
