Ladies' Night by Mary Kay Andrews

Grace Stanton has built a successful career online with her home-living blog, Gracenotes.  But when she catches her husband, Ben, in a compromising position with her assistant, J'Aimee, she impulsively drives his Audi into their swimming pool. Grace then moves in with her mother, Rochelle, upstairs from the Sandbox, a bar that she's owned since Grace was a girl.  As part of the judge granting Grace and Ben a divorce, he requires that Grace attend group therapy sessions. Furious at the judge's decision and without any money (since Ben has cancelled her credit cards and frozen their bank accounts) Grace tries to stay positive--even after Ben has shut her out of Gracenotes.  With the support of Rochelle, her fellow members in her therapy group, and maybe a possible romance with Wyatt, the owner of Jungle Jerry's (a dying family fun park), she just might turn her life around for the better.  Ladies' Night is a humorous, breezy read with an interesting setting on the gulf coast of Florida, combined with lively characters and a bit of romance.
