Seeing Green. Pine Hills Book 3 (en Inglés) - Laramie Cummings

For over a decade, Emma Manning had been utterly smitten with her older brother Everett's best friend, Joel Clarence. A first kiss that turned into a secret night of utter passion was a moment they both swore to keep forever, convinced that a hidden romance was all their complicated love could ever amount to.
Now, years later, Joel is finally ready to chance his friendship with Everett and lay his and Emma's relationship bare for all to see. But before he can, Emma, with a suddenness that leaves him gobsmacked, ends things abruptly. A few short months later, she announced to their entire circle of friends that she was off to the Emerald Isle, taking on the role of Chief Technology Officer for a tech company in Dublin.
Heartbroken and furious, Joel is left behind in New York City, surrounded by the ghosts of Emma's life. As he gets ready to ship off the last of her belongings, he stumbles upon what he suspects is the crushing secret she'd been keeping. Spiraling, Joel takes time off to wander the world and mend his broken heart, wrestling with the thoughts that have him believing the girl he's loved for ten years is his soulmate, but might never truly be his again.
Emma, for her part, is running. Not just towards a dream job, but away from a devastating truth she can't share, convinced that leaving Joel was the only way to heal her aching soul. But when their paths cross again over St. Patrick's in Dublin, the secrets they've held tight will either be their undoing or be the stroke of luck that finally brings them back into each other's orbit.
Will they be able to find the pot of love at the end of the rainbow and be together, or will the crushing weight of their past and the complexities of their present keep them from finding their own lasting love?
