I've been thinking of this book for days, but I cannot remember the author or the title.  It's a contemporary western romantic suspence.  A single mother moves west with her son and buys a diner.  She wants to create the old time feel and has the wait staff wear dresses. She meets a rancher and his friend at the diner.  She and the rancher strike up a friendship that turns into more eventually.  The rancher is beholden to a father figure and feels he needs to marry said father-figure's model daughter.  There are some environemental issues going on and the diner owner sets up a command post of sorts in the back room to fight the bad guy environmentalist.  She gets attacked in the diner in the dress and after that decides jeans and t-shirts are okay.  Towards the end of the book she is on a forum online while she is attacked in her home. 

I'm sure this is very vague, but that's what I remember.  Thanks for helping.

If you have LibraryThing, they have a Name that Book Forum.  You may want to try there as well.  I asked my mom, who is an avid book reader and she didn't know.  She said it would help if you had a general idea of publisher and publisher date.  That would eliminate options.
