Hiya, I had a good long chat with a few of my betas, and based on their input I kept Darrienia as a full length novel.
When I checked the pricing for the cx, it would cost them more if I split the book, truth be told, I set my royalties very low to make it affordable. However, I didn't feel that splitting the story would enhance the reader experience. In fact, I would have felt like I was cheating them.
Of course this probably means I have reduced my audience, the size of the book means it will appeal to perhaps fewer than if I had found a split, but I am happy with the choice.
Just a point of interest, the second book in the series is nearly as big, I am just editing it now, (or should be but popped on here instead) One thing I will do however, is make the chapters shorter. My chapters in Darrienia are quite large, though there are breaks etc, but in book 2 they will be better.
I did consider however, for book two, splitting the paperback but leaving the kindle as a complete one, but I recently decided against that too, the first 2 books in my series are almost a uniform size, the third and forth are smaller.
On a side note, I read a book recently that was spilt, I got to the end of the first and I was super disappointed because there had been no conclusion, yes there was a cliff hanger, but it seemed more like the author went, 'ah here, this'll do' *ends book* rather than tying up some of the events and leaving on a cliff hanger. Then book 2 starts at the exact moment book 1 left off. As a reader, it really annoys me, so looking back, I am really glad I didn't split it. When I did my writing course, many moons ago, I was always told that a book in a series must also work as a stand alone piece and the issues, but not the running theme, should be resolved, leaving the reader to feel like they have reached the end of that book, but wanting to know more about what happens with the continuing background story.
My advice, it's too soon to say if the size of my book has put people off, but I have had 6 5 star review since it was released in September (and might I add not from family etc), I sent my book to two reviewers, who promised a genuine and honest review in exchange for a free copy after I pitched the book to them, and they both gave it a brilliant review. If you can split the book without cheating the reader or breaking the story, then do so, otherwise, I would leave it as is. But that's just my thoughts on the matter, and I am sure there are many who would disagree.
