Forever by Maggie Stiefvater
The only reason that I haven't read this book yet... is because I don't want the series to end. :( I love this series and I tend to avoid finality. So this book has been sitting on my shelf for a couple of months and I'm just scared to even look at the first page. I know I'm going to love it... I've looked a few reviews and they say the ending is great... but I'm a little hesitant because I don't want the series to end.
Other series I'm dreading the end to: Hush,Hush by Becca Fitzpatrick, Wings by Aprilynne Pike, Fallen by Lauren Kate, Hex Hall by Rachel Hawkins, and Unearthly by Cynthia Hand (luckily I've got a couple years left for that one)
What are some series that you are dreading the end to?
