There's a point to this rambling. and like I said, it's not about reviews. It's about series. Right now I'm writing another book that has Joey and Aaron from Collision Course in it as secondary characters and they are about two pages from hitting the stage. I think back to that conversation with and I get nervous. Not about reviews, but because of wanting to do right by the story, my characters, and the reader. I want to deliver the kind of connection with the characters that the readers who've been asking for more will enjoy, while not pissing off anyone who reads it no knowing them. Sequels or connected books should always stand alone. I've come into series out of order and the writers have been kind enough to let me in. I've also been there since the beginning and enjoyed sharing with the writer that in-joke, a trace of "Yeah, that's how we go on" that feels familiar and cozy and like hanging out with old friends.
There's a reason series are popular, from my childhood friends like Trixie Belden and The Black Stallion to any of the latest series books gracing the bestseller lists. There's a reason publishers, authors and agents love them. They come with a built-in readership and following. Sometimes as a writer, they feel like the easiest and the hardest thing to do. The world buildings done—but you're stuck with what you've done before. There are characters already made, but you'd better not bore new readers with them or make assumptions.
And if it could unnerve a NYT bestseller like my acquaintance in the first paragraph, the weight of that expectation hanging pretty darn heavy on me as Joey and Aaron are making their way onto the scene. I'll try not to make them seem "beloved by all."
The book is Dylan's story and if all goes well, you should be able to get it when things get warm here in the Northern Hemisphere.
