Roadside Attractions by Mara Quinn

Stella and Roman were supposed to be forever.

However, that was before Roman left Stella with nothing but a note detailing vague plans to “find himself” and see new places. Now, it’s just Stella, her broken heart, and an extra half of the rent to pay.
Enter Wyatt Song–free-spirited, infuriatingly attractive, and a notorious player. Roman’s best friend, and the bane of Stella’s existence. As it turns out, Stella isn’t the only one Roman screwed over, and there’s nothing like revenge to bring together two people who can’t stand each other.
One uncharacteristically impulsive decision later, Stella ends up on a cross-country road trip to track down her ex with his (former) best friend. Somewhere along the way, between dodgy accommodations, car troubles, and misadventures, Stella finds herself battling her unexpected, and undeniable chemistry with Wyatt.

The last thing she needs is to fall for someone new when she’s fresh off the heels of her heartbreak. But this whirlwind of a trip may not give her a choice in the matter.
