I'm all for tormenting the characters I bring to life; that' s my job as an author. But I am tired of reading series in which drag on for 20+ books and yes the characters have grown a bit but they make the same stupid decisions from book 1.
There is a fine line in building the story of the character so we can see a change in their life choices and twisting the character's world just for your amusement. Write a series with a stopping point in mind. Authors, please don't pull out your character's nails just to create drama and tension for the series to have a bigger plan than that.
Thanks, your faithful reader,
