NaNoWriMo Plot...

So I wanted to share my planned plot for my NaNoWriMo novel and get some feedback on it.

Feel free to leave a comment : )

So I plan to call it: What Goes Around

Here is the basic plot synopsis...

If you could ruin the life of an ex, who broke your heart, would you?

5 years ago, Alexa's heart was broken into a million pieces by a colleague.  Josh, who broke of their engagement 3 weeks before the wedding, was Alexa's life.  She had to request a transfer and build a new life for herself in a new town.

Now 5 years later, Alexa likes to think that she is older and wiser.  She has a sweet boyfriend, has been promoted and is in a place in her life where she she feels happy.  That is until she finds out she is getting a new person in her division.  When she finds out it is Josh, all the old memories come back up.  At first she is nostalgic and nervous when he starts working there, but soon all the repressed anger she has starts to surface and the memories of their relationship lead her down a dark path.  One where she is determined to make him pay for what he did.

Alexa uses her position of power to slowly ruin not only his career but his life.  All while trying to maintain an outward appearance of a professional and friend.

So what do you think?  Does it sound like a book you would read?  It is supposed to be light read, sort of a dark comedy beachy read.  Thoughts?
