I can’t think of the last time I thoroughly enjoyed the second book in a trilogy.
I have no idea.
The problem is that the first book is about building up the world/story. You’re getting to know the characters and that’s FUN! You’re getting to know the world and that’s INTERESTING. You’re being introduced to an intense plot and that’s EXCITING.
Then, skipping ahead a bit, book three is about wrapping things up. There’s the huge climax you’ve been waiting for all series, an epic showdown, and a satisfying conclusion (hopefully).
Where does that leave book two? Well usually, it’s left bridging the gap between the two epic books. But being a bridge isn’t all that fun. It’s just setting the scene for something bigger and better that will happen in book three. It’s not as new, fresh, and interesting as the first book. It’s not as epic and intense as the last book. So where does that leave us?
Too often, I think that second books are “okay”, or “not as good as the first book”, or “good, but not great”. I’m sick of being let down with the second book! That often leaves me deflated and not as excited to read the third book.
