How many characters are too many characters to introduce into a book?

It can be difficult at times to keep track of the characters but 15 sounds like plenty. Hopefully as you get into the book more they will sort themselves out.

I wonder if there is a limit on that. Fifteen seems like a lot of characters. But then again, I've been reading a book by Cassandra Clare in the Dark Artifices Series and there are probably more than 15 characters in there.

My first novel had a lot of characters but they were separated into their own different stories. They were introduced at the beginning though. Just tell me it's not my book you're reading and lost interest in. LOL

I dislike books with too many characters, I also have difficulties keeping track who is who.

If they enter in more than 12 characters, they lose me all together. It's hard to keep those personalities and figures straight, in my mind's eye. So I lose interest and stop reading the book.

Basically, there is no limit to how many characters there can be in one book. It's totally up to the writer how the book is written. But, writers are people too. Unless the characters being introduced is in context with the book, then it's going with the flow of the book which is most likely the idea of the book introducing many characters. Like good stories we watch and enjoy on tv, it has constant characters you get to know and the story is built around, is the same as a good book. You can check here too about characters in a book:
