Summer Rental by Mary Kay Andrews

Ellis, Julia and Dorie have been best friends since Catholic grace school.  Ellis, recently fired from job she devoted her life to, has put together a plan for the three of them to stay at a rented beach house in Nags Head, North Carolina.  Upon arrival Ellis finds that the house isn't all it was advertised to be, and the illusive owner/manager is hard to pin down, and the tenant over the garage is suspicious. 

So starts a month at the beach.  Each women arrives with secrets and a heart in turmoil.  Dorie has a chance meeting with a women, Maryn, who is looking for a place to stay.  Dorie is feeling guilty about money because her sister was supposed to come along on this trip and backed out at the last minute, which means that there will be more money owed by each of the three women.  Money that Dorie doesn't have to spend.  She asks Maryn if she is interested in renting the top floor of the house without discussing it with the others, and Maryn accepts.  Maryn is hiding out and decides that this is as good a place as any to get herself together and decide what to do next.

The girls are in for an adventure none of them good have expected.

I wasn't expecting to like this as much as I did.  A very pleasant surprise!
