HI phoenixx50,
Pretty much what Andrew said --
It reads a bit like a tagline as opposed to a logline -- to avoid that it's a good idea to reveal specific events that propel the characters through the story, as well as specifics about the characters (or character) so we the readers know who this story is about and what they have to do; i.e. state WHO these woman are (High School Teachers/ High School Clique now all grown-up/ Neighbors/ etc etc etc...) and what the main issue IS:
"Three young professional woman, a former High School clique, reunite after the death of their undeclared leader, and help each other through their own addictions to deal with each others grief."
...nqr... but I hope that helps...
Best of luck.
