Two Doors Down by Olivia Monroe

When Aria moves into a new building, the last person she expects to see is her best friend’s brother, Eric. Although a decade has passed since their last meeting, it is abundantly clear that the fire of an old attraction still exists and there’s not much that will stop Aria from getting steamy with Eric at the first opportunity. Except for Jenna.
She is Eric’s sister and Aria’s best friend. She isn’t so keen to see the two of them hooking up and makes her feelings known, forbidding any romance to take place between them.

Can they find a way to be together without damaging Aria’s relationship with Jenna? Or will Aria choose her friend over her desire to get close to Eric?
