I'm looking for a romance novel.

elements in the novel include.

1.  A movie is being made of a legend which goes a red headed egyptian
princess gets kidnapped from her family.  Her captor falls in love
with her and loves her so much and wants to make her happy so he
returns her to her family.  Unfortunately she is shunned for being
unchaperoned in the company of a man and her captor comes for her and
they live happily ever after.

2.  The egyptian story isn't the story being told it is a subplot told as a legend.

3.  A woman who is an actress wants to play the egyptian princess in
the movie.  She goes to a casting call and gets the job.

4.  The actress whose name is Caitlin finds herself in love with her
sisters husband on her sisters wedding day.  She is confused and a
stranger takes her out of the party so that she won't humiliate
herself.

5.  Her sister a few years after her marriage is in a sking accident
and Caitlyn needs to take care of her sister's family.  She has since
learned she is not in love with her brother in law.

6.  Cait's future love interest the guy who pulled her out of the
party.  Winds up living in the apartment above Cait's.  She is having
a party one night and she is dancing for her guests.  The way she did
for her college buddies.  The soon to be love interest walks in on the
scene and makes a rude comment.

7.  The love interest turns out to be an actor too. He is to play the
eqyptian princess's captor in the movie.

This list is not in chronological order of the story.  It's elements
in no particular order.

I did quite a bit of hunting when you asked this question last year,
and never turned up anything useful. At that time you said that the
main character's name might have been 'Lorelai'. Just thought I'd
mention this, in case it gives a Researcher a clue.

Thanks.  The characters name could be Caitlyn or Lorelai.
