Spoiler warning for Shadow Kiss (Vampire Academy Book 3) by Richelle Mead ahead. *Not a series I stopped reading.*
I read mostly YA series, and I've been noticing one trend popping up lately. Somewhere in the end of the 1st or 2nd book, the intrepid heroine gets together with her true love. Then, in the next book, she spends many many chapters swooning over him, stating how perfect they are for each other and how they're going to be together forever. All this does for me is throw up a red flag that says, "Warning: These two characters will no longer be together by the end of this book."
Boring. I don't want to know the end by page ten.
Let me give you an example of a plot reversal involving the intrepid heroine and her true love that I felt worked. In Shadow Kiss, Rose and Dimitri finally get together in act 3. But, because of the age difference and the fact that he's her teacher, they both know it's going to be anything but smooth sailing. Still, you have hope for them. Until a couple of chapters later when Dimitri turns evil.
This was a reversal I didn't see coming, and it provided Rose's motivation throughout the 4th book and part of the 5th one. Plus, bonus, I didn't have to sit through chapter upon endless chapter of Rose driveling on about how happy she was. I like it when my heroines aren't allowed to breathe until the very end of the last book. If they're happy for too long, it just gives me time to imagine all the nasty things that are going to happen to them. Things I want to happen to them.
What about you? What makes you stop reading a series?
