I am starting my second book in a series. I am struggling a bit with how to clue the reader in to what happened in the first book and how to introduce the characters to a new reader without being repetitive for someone who read the first one.
I am assuming that even if the book does follow the first, someone should be able to pick it up without reading the first book and be able to understand and enjoy it.
Got any favorite tips?
How much information goes into the later book(s) depends, I think, on whether you want this to be an inter-connected series with an overall story arc, or if they are going to be standalones featuring the same character(s) and / or world setting.
At the moment, I write "closed" series, by which I mean a series with an over-arching series arc that plays out over X number of books. The series arc doesn't continue beyond the final book - if I wanted to keep writing in that world, I'd have to come up with a new series arc, or do a spin-off stand alone(s).
(As an aside, I was watching one of the short tips videos on the Self-Publishing Formula recently and apparently that kind of series arc means I'm really writing serials - despite the books being 80K plus words - but I think most everyone calls them series.)
For my first published series, I really struggled with the opening of Book 2 trying to work out how much / how little information to put in - I don't think I got it right at all as I feel the opening is really heavy, trying to catch the reader up on where we are. In later books I kind of gave up, and just dumped the reader straight in. I haven't had any complaints about that.
Personally, it drives me crazy when an author over-explains past events in the current book (there's at least one trad-pub author I've stopped reading because of this), but occasionally you do need to be reminded in a long-running series of where / when something happened.
In some ways, I think standalones might be easier because you know the reader can drop in at any point, and therefore you have to give them some basic grounding every time - I'd have a look at something like the Jack Reacher series which, from memory, doesn't really give a huge amount of background each time.
Not sure that's any help at all - I'm definitely on a steep learning curve with this, too!
Best of luck.
