Great title, Gerri Garrick! This sounds like an exciting story!

I think your logline needs a little work. I have three suggestions:

#1) I think your logline needs the inciting incident (how they got stuck in the past).

#2) I suggest changing "must work with her sister, an uptight executive" to "must work with her uptight executive sister."

#3) Mention what they have to save Amelia Earhart from.

So, something like: "After being sucked into the past, a flighty free-spirit must work with her uptight executive sister to save Amelia Earhart from ______ or be stuck in _____ (the year of the story) forever."

Or: "A flighty free-spirit must work with her uptight executive sister to save Amelia Earhart from ______ or be stuck in _____ (the year of the story) forever."

Oooh. I love the first one Maurice. Thanks! They have to save her from dying on that historic fatal flight, btw.

I should say, infamous fatal flight...

You're welcome, Gerri Garrick. I like that. So, "After being sucked into the past, a flighty free-spirit must work with her uptight executive sister to save Amelia Earhart from dying on that infamous flight or be stuck in 1937 forever."

I put "infamous flight" instead of "infamous fatal flight" because the logline already has "save Amelia Earhart from dying on," so we know the flight was fatal.

I Like that! What do you think about the above tweeks?

I like your logline, @Gerri Garrick! I don't think you need a comma after "sister" though (since you have a comma after "fate," which I think you put so whoever reads your logline won't get winded).
