Desiree,
I like the description of Logan . . . spot on!
Have you considered a story arc for the series?
At some point along the way, I think I was still writing the first one, I realized I didn't know what to write about after the second book. I had a bunch of titles that had been brain stormed, but they were just empty titles. So I looked at each title and gave it a story idea - a phrase or sentence, no more. Then I juggled them around until I liked the story arc of the series. Also, I noted that there was some missing pieces.
For example, what is now going to be the fifth book is modeled after The Empire Strikes Back in the Star Wars series. Not the story, but that the bad guy starts out kicking my protagonists butt. This would be the same as the second disaster in a book story arc. So she gets her but kicked and is floundering around from bad spot to bad spot, to eventually blow up the metaphorical death star and wins in the end.
If I hadn't done the overall series arc I wouldn't have seen that there was a place to have her flounder like you do in a book after the second disaster.
Of course, if you choose to do this, the number of books in the arc is totally up to you. I have the first nine books laid out in my series arc. It is much less stressful now that I know what each book will generally be about.
When you are ready for beta readers, post it on the beta reader thread and PM me. I am always open to an exchange of beta reading.
