Laura Heffernan 
The Accidental Senator [EPUB ebook] 

Lana Chen’s just been elected state senator. Weird, because she wasn’t running.
Well, practicing law was getting boring anyway, so Lana dives into the deep end. She seeks guidance from Senator Jason Park and irresistible lobbyist Steve to navigate the shark-infested waters of politics. Then someone she trusts tricks her into casting the deciding vote for a bill that spells disaster for the community—including her best friend's brand-new pole fitness studio.
There has to be a way to stop it. If Lana can't undo the damage she caused, she's going to lose the support of her community and the most important person in her life.
