Why did it have to end???

I was quickly lost within 'Never Cry Wolf'... full of action, fast paced, loving the interraction between Jade & Reece, then next thing I knew I was finished... WHY did the story have to end??? Everything within the story was thought out, giving me a little bit of history from both lead charactors & then they interract & everything just meshed so well. I can't wait to read what Catherine writes next...
