Halo by E.M. Lindsey

One mistake: Victor got into the wrong car.
One decision: Oliver didn’t kick him out.
One lie: neither of them knows who the other person is— at least, not until it’s too late to turn back.
There are many words for what Oliver does for a living, and none of them are very kind.
But Oliver’s time in that industry is nearly at an end, so when a gorgeous older man with sad eyes tumbles into his path, Oliver finds it impossible turn him away.
Victor looks at him like he’s an angel, even when Oliver feels like a devil, but he knows better than to hope. After all, men like them are only ever destined for star-crossed love.
But as months of separation carry on, Oliver realizes that maybe he really is willing to fight for what he wants.
And, more importantly, for who.
