I posted this once before, but some how all that posted was the title and not the description so I'm gonna try again, lol!

the book I'm looking for....the heroine is from the city and comes to the ranch with I think they were coworkers that she really doesn't like they are very snobbish and shallow. She then meets the hero who is running the ranch although unknowing of the heroine actually lived in the city too. They immediately get off on the wrong foot and somehow she ends up shooting at a snake at his feet. He is then infatuated with one of the coworkers who came with her and these sort of instances keep happening throughout the book until something happens and he has to leave their camp and his identical twin takes his place and she realizes that he is not the hero. Which leads the twin brother to inform her that twins run in the family and the only person other than family that can tell them apart is their true love. This leads the heroine to swear the twin brother to secrecy. Then she runs into the twin later and calls him by name before she realizes the hero is also present. At the end she goes back to the city and I believe he comes after her by landing on her balcony from a helicopter. I really would like to find this book to read again, but I can't remember the name of it!! Any help will be greatly appreciated, thanks!!! :)

I can't place the book, but the idea that the true love is the person who can tell the twins apart is very common in Jude Deveraux's "Montgomery" family series.

The story can be found in the book titled The Invitation by Jude Deveraux a 3 book novella with these three titles in it.   the invitation, the matchmakers, a perfect arrangement,  the title of the one in the description above is THE MATCHMAKERS.  on my keeper shelf :)
