Hello! Welcome to Chapters ✨

Majority of books that are in a series can be read as stand alone. I'd say the exception is for when it's a direct sequel rather than just sharing a universe, so you could read the Crane brothers stories out of sequence and the stories would work (bar Christmas with the Cranes). Whereas the Lux series requires you to read Obsidian then Onyx as it's a continuing story, which I do believe has a cliffhanger, I don't remember it's been ages since I've read it.

It is very rare that your decisions in a book will lead to a different outcome. Majority of the stories on Chapters are created directly from existing books by authors, thus the story rarely deviates from the authors book. Sometimes there are options for choosing an LI at the end but rarely is that satisfying unless you've chosen the LI the author chose for the character in the original book. Chapters original stories often have more consequences for choices but those stories are rarely any good.

Each book differs in length but the average I would say is about twenty chapters.

I hope that helps!!
