A gentleman by the name of Nicholas Rossis contacted me for help with a series overview for his books, which are No.1 in the Amazon rankings.
Here's what I said. You can get his books at http://www.amazon.com/Pearseus-Prince-Nicholas-C-Rossis-ebook/dp/B00FYRKLPI/
Think about these points:
Characters Good v. Evil
Drivers (usually emotional)
What happens if they fail.
You have to be fairly functional and matter of fact in a series outline. You lay out exactly what it is as a series.
e.g. The Pearseus series an epic fantasy/sci-fi story told over x number of books.
I've used this because you've kind of described it as such to me
already. So use that. Just how would you tell someone about it, as a
series if you were having a conversation about it? That's what you
should say in your series blurb.
Consider what your theme is, not what the books are about. I say this
because each writer, no matter the book, writes about the same theme
every time. This is something integral to you as a human being. It's
what drives you. Each story you tell is an investigation into your
theme, but told differently each time.
For instance, I realised fairly early on in my writing career that the
over-arching theme of everything I write is survival, and the things
people will do to survive. Sometimes, it's mixed with secrecy - the
things we keep secret so that we can survive. It doesn't matter what I
write, or what style I write in, or the subject matter, it's always
Most stories are actually about survival in some form or other. Knowing this makes it easier to formulate an over view.
Also, consider this: you will find lots of references to there being 21
stories, or 30 stories, or 7 stories etc… in the world - and that all
stories fall into one of the categories they cite. However, I've found there
is actually only one story. Wow! One story, I hear you say, how come
all books are so very different? And what is this one story?
Well, that one story is the quest. A quest for true love. A quest for
treasure. A quest for a new planet. A quest to capture someone. A quest
to win the war. A quest to survive in the face of a storm, or ghost, or
enemy. It's always a quest. THE quest.
This being the case you simply look at your series in terms of the
quest. What is the theme? What is the quest? Forget individual story
arcs etc… just focus on the theme and the quest.
I'd say you're fairly safe with it being about survival and the things
people will do in order to survive. Don't forget humans are hot-wired to
survive in three ways - as individuals, as families and as species. We
fight first as individuals - for ourselves. We fight second for
family/tribe/country. We fight third for the species.
So, you have an introduction that tells people what the two books are - a
series (with potential for more I assume), and that it is about a bunch
of people on a quest to survive against all the odds on a hostile
planet. During the duration of their occupancy they come up against
various enemies/problems etc… which test their resolve over a long
period, giving the reader the opportunity to get involved with the
'world' you have created.
