Rumi: The Hawthornes by Nicole Jacquelyn

Rumi Hawthorne and Nova Tomlin have been best friends since the summer they turned thirteen. They know each other better than anyone, witnessed every bad decision, bad haircut, and bad mood.
By tacit agreement, they’ve kept things strictly platonic.
Until one drunken night.
Rumi refuses to settle down before he’s forty. Nova works two jobs, single minded in her determination to save enough money to go to school.
Neither believes a relationship is in the cards.
But, now that the line has been crossed… fooling around doesn’t seem like such a terrible idea.
What could go wrong?
