Déjà Vu by Allie Hayden

Modern day New York, unrequited love, and one chance to go all in.
Childhood ex-lovers Sebastian and Lillian have been separated since they were teenagers.
After more than a decade, they find themselves coincidentally back in the same city.
Lillian is with someone new—the sexist heart throb this life has to offer, Ash Bennet, lead singer of Dreams of Compass Gods and every girl’s mad desire.
Sebastian is forced to watch from the sidelines, doing what he can to move on.
Being an attractive lawyer himself, he has no problem finding a girl to fill his lusting frustrations.
But what’s the point of getting any girl if he can’t have Lillian?
He’s tried all the routes, all the ropes.
If he can’t get over her, he’d rather get her back, so Ash better watch out.
The goal? Risk everything to get a second chance.
The lesson? Love will make you do stupid things.
