The Five–Star Weekend by Elin Hilderbrand

First, there's Tatum, Hollis's best friend growing up on Nantucket - and her husband's best friend, Jack, who just happens to be Hollis's first love.
Then there's Dru-ann, her best friend from college, now a prominent Black female sports agent in Chicago, whose Twitter comments have just landed her - and her marriage - in hot water.
Brooke is the best friend who helped raise her kids with Hollis during their thirties, until she was ousted from the local mum's group by Electra, self-appointed queen bee. But Brooke and Electra are finally meeting up to make amends this weekend...
And lastly, Gigi, who reached out to Hollis on her food blog to become 'internet besties', but has never met her in real life.
All the weekend needs is Hollis's daughter Caroline, a documentary student, who wants to film the entire party... What could possibly go wrong?
Filled with the emotional depth and trademark cast-of-characters perspective of Hilderbrand's novels, The Five-Star Weekend promises a story of a remarkable weekend between friends - old and new - like no other.
