It’s worst with TV & Cinema, not knowing when to stop. I’ve two major series, one SF and one Fantasy. The temptation is like Pern or Chalet School and to keep extending. Except unlike the the Famous Five the characters age and change. Unlike the excellent Midkemia world, both have major social, political, economic and technological changes. The Celtic Otherworld of the Inamok development somewhat influenced by my own engineering background and interest in vintage electronics. I wrote a history of Communications and Computers with their convergence in the 1980s as a background for a project. I also spent many hours with Civilisation II and IV. Those games seem well researched. All influences of the Celtic Otherworld series.
I think “Carmán’s Legacy” (book #14 of Celtic Otherworld) and either the “Mission’s Talent” or the “College Talent” (#7 and maybe #8 of Talent’s Universe) will tie up all the loose ends. I’ve chopped up the “Second Talent” and put bits into “The Legal Talent” and “The Mission Talent” as it only reached Novella length and the plot was weak.
I have the “Restoring the Talismans”, once Jorath’s Quest (started in 1992) and a sequel, now combined as a stand-alone story needing re-written.
There is the start of the hard SF, “The Eden Seeds”, but I’m not sure about it!
My plans for a 16th Century Adventure / Romance are taking shape. I need to do a lot more reading and research. In a way it’s the start of a new Era in Western Europe with exploitation of the Americas starting. An acceleration of the loss of Celtic Ireland started with Henry II in the Twelfth Century, when he obtained by political trickery what had never been achieved militarily, Brian Boru’s victory at Contarf in 1014 was really the start of the end because there was no political reform or cohesion in Ireland, making the political success of Henry II inevitable. A setback for the English was avoided in the 14th C due to famine and defeat of the Scottish King Bruce’s brother’s Scottish army in Ireland. So I’ll be concentrating on the Rígan Gráinne Mhaol (Grace O’Malley), an almost exact contemporary of Queen Elizabeth I, died the same week. Very likely QE I, Walshingham, both Marys and John Dee will have parts.
My rooks (in six books) have been well received, so I may do something for younger readers in the line of “Watership Down” (not a child’s story), “Farthing Wood”, “Duncton Wood” but not “Wind in the Willows” mainly featuring cooperation and enmity between various members of the Crows in Ireland. Jackdaws and Rooks are social. Magpies are not much liked by any bird. I’ve seen them take a tit from the bird-feeder. The hoodie crow, carrion crow are less social. Ravens seem rarer. Rooks are certainly very smart tool users, can count, have a vocabulary, recognise humans and guns but are very lazy. Illustrations or at least my own photos would be nice. I’ve just evicted a jackdaw pair from my attic. The third eviction of crows.
