Now, most writers want to continue their books to make a sequel or even a series but there are some things you need to consider when writing a M/T sequel book.

1) the plot needs to be as action packed as the last book, you can't just have a book that is just talking about the glory of the last book.

2) treat the sequel almost like the first book- don't slack on it. Make it just as complex and thrilling as the last book, hell make it more thrilling.

3) develop your characters EVEN MORE.

4) learn from the mistakes you made in the first book and use those to hook people into your sequel.
