The Last Summer by Brandy Bruce

For twenty-something Sara Witherspoon and her group of friends, a perfect Southern summer includes lake-house getaways, wedding planning, outdoor concerts, and a dash of romance. But for these seven friends who love each other like family, this year, summer rolls in with changes for everyone.

Sara’s longtime crush, Luke, has been her best friend for as long as she has been a part of the group. When Luke begins seriously dating another of their friends, Sara’s forced to deal with her hurt and jealousy, while outwardly try to support them both.
While Sara comes to terms with her own heart and her friends’ relationships, an unexpected handsome pilot from North Carolina and an old flame are thrown into the mix. Knowing her heart suddenly becomes much more complicated.

But as time unfolds and friendships begin to unravel, Sara and the others are presented with the reality of what a season of change does to old friendships and new love interests.
Does growing older mean growing apart?
