Time Slipping

So. I finally got my hands on this book. Therefore, I finally finished this book less than 24 hours after I got it, which implies that this book was AMAZE-BALLS.
But gosh darn it, that ENDING. That...Elle Casey, you can't keep doing this to your fans .-. What I mean is, you can't keep ending your stories like this and forcing your obsessive readers to wait at least ONE YEAR for the next book. It's just...not done.
I didn't like this book as much as the other books because certain things didn't happen that I wish had happened after certain situations developed through the book. What I mean is, I wish the party that went with Jayne to that other realm had apologized to Jayne for believing she had hurt Felicia for no good reason. Or something like that. Or maybe Jayne's view of her friends' attitudes was tainted by the cut she got from her demon sword...Eh. But still. I never liked the succubus twins .-. I also didn't like how Jayne was separated from her group for most of the book.
My having so many questions isn't necessarily a bad thing but it IS driving me crazy.
