Falling for You by Virginia May

Grant lives life to the fullest. He owes it to the brother who’ll never come on another adventure with him.
Chrissy would love to live life to the fullest, if only everyone would stop treating her like she’s fragile. She missed half her childhood being sick; she’s not going to let it affect the rest of her life. At first, Grant seems like the ideal companion in her search for all the things she’s been missing – bold, beautiful and larger-than-life, he’s everything Chrissy would like to be. Except, as she realizes she’s starting to fall for him she notices something else: like her, he’s broken inside.
Love is a great healer. But can it mend these two damaged souls?
