Sparked. The Beckmeyer Family, #2

Nina Beckmeyer had been in love since she'd been sixteen. There was just one problem. The guy had no idea. After spending two summers and countless weekends with her family, Donovan Stewart was gone in the blink of an eye. All these years later, she's doing just fine even if all her dreams are of a man she knows she can never have.  Until he shows back up. Donovan has loved Nina since the moment he saw her thirteen years ago.
It happened in a flash and has never gone away. But she's his friend's sister and there is no way Emmett would be okay with them together. Or would he? When he arrives in town as a favor to Nina's family, the same spark of awareness that had been there so many years ago, is even stronger. Donovan knows it's now or never and he's not willing to settle for never. Is the love they each secretly felt all those years ago, a love that is real?
