Chasing Fireflies by Addison Clarke

Mason Mackenzie has never been good at relationships. Casual hookups she can handle but anything involving commitment is a stretch for her. But the older she gets, the more she begins to loathe the lifestyle she’s become notorious for. Her track record proceeds her in all the wrong ways which leaves Mason to think she’ll never find The One.
Chase Monroe has been Mason’s best friend for years, but they’ve never crossed the line of something more. Not that Chase doesn’t want there to be more. She’s often found herself wanting a relationship with Mason that was more than friends. Especially after her fiancé left her after a terrible accident. But can she really be more than friends with Mason?
When out for drinks one night, Mason and Chase agree to give friends with benefits a try. Mason is hesitant at first, knowing her feelings for Chase will make it almost impossible to keep things casual. But how can she say no to those blue eyes looking at her?
Can these two best friends keep things casual? Or will they realize they are destined to be something more?
