Writing a science fiction series: building recurring ideas from book to book

I like to view Series as one longer story, told in parts. Although each book may have its own story and character arcs, there is continuity between books. Books in the series may share characters, settings, world view, spiritual beliefs, mythologies, principles of chemistry, biology and physics and so on.


Books in a series may also build, from book to book, on ideas not explored fully in earlier books.


Examples from my own books about adventures on the planet Meniscus include the story of Belnar’s missing tooth.


'Belnar' paperback


Belnar is a Slain, a genetically modified Human. Like other Slain, Belnar has exceptional endurance and strength, has unusual physical features such as nictitating eyelids, and uses electricity for protection and weaponry. Belnar also has a personality different from other Slain – he is brash, a joker, self-serving, irreverent and aggressive. In an encounter with another Slain, Belnar loses his front incisor. A small physical defect causes him to have pronunciation problems but he uses the defect to advantage, mostly to make himself seem more charming.



Although not critical to any particular story, Belnar’s tooth (or lack of tooth) recurs, story after story.

Crossing The Churn – Odymn finds Belnar’s tooth in a packet of Daniel’s contract trophies

'a trophy for every contract'

South from Sintha – Odymn and Daniel release Belnar from the island where he is a captive and the story of the tooth’s loss is described

Winter by the Water-climb – mentioned as a physical feature

The Village at Themble Hill – the missing tooth and the whistle in his speech help Belnar make friends with an alien child

Karst Topography – Belnar gets a dental implant in Prell to make Vicki like him

Encounter with the Emenpod – Belnar gets in a fight with another Slain and loses his brand new tooth


'the Slains battle'


A small idea, the story of a tooth, but recurring ideas serve a few purposes in a book series:

  1. The missing tooth is a symbol of Belnar’s edgy personality,
  2. The missing tooth is a metaphor for recurring problems that never seem to be resolved
  3. Readers familiar with the series watch for recurring ideas and feel an ‘insider’ connection
  4. Later stories in the series may seize on a well-developed idea with ‘history’ and use such an idea as a plot focus.


Who knows the future of Belnar’s missing tooth? At this point in the writing of the series, it remains an idea rife with possibilities.


If you are writing a series, do you introduce recurring ideas to serve story-building purposes?


All my best,
