I want to write my book series as a series of short novellas (about 150 pages each) with each book forming part of the storyline.
The majority of books written with comparable lengths are intended for a younger demographic who may not be able to finish a longer story.
However, my series will be targeted towards an older audience (teenagers and adults). I am concerned that publishers will be unwilling to publish my book series since I have not seen young adult literature written in this format before.
Each book in my series will have a different "feel" to it, which is why I am planning to release it in this format. The only alternative I could think of is publishing the novellas in an anthology, but the novellas do not feel interconnected enough to publish in one volume.
I am also planning to include maps and fictional documents as an addendum at the end of each book as a substitute for illustrations.
Has any commercially successful young adult series used this format before? If so, has the publishing market significantly changed since then?
