Q: I read somewhere that your book is 113,000 words. Isn't that too long for a debut author?
Funny you should ask. I thought the same thing, like, oh crap, Jill is going to scream and throw things when she sees how freaking huge this is. But all she said was, "it is long, but I really feel like every scene is necessary." #EditorLove :)
So that's the short answer. There is no too long or too short. There is only just right, the length your book needs to be to tell its story. However, I realize this answer is totally unsatisfying, and to be truthful 30,000 words is probably too short for a YA and 250,000 words is probably too long for, uh, anything. (Good news. You didn't write a novel. You wrote THREE novels.)
I have gathered together the word counts for some of my favorite YA books, just to give you an idea of where you stand. For more great word count info, including the secret to finding out exactly how long most books are, check out this post over at my awesome agent's blog.

Obviously there are some trends within the different genres, but if your YA book is falling somewhere between 40K and 120K words, there's probably no need to panic. However, the rules of good writing trump the hard numbers every time. Infuse dead passages with sensory detail. Tell the whole story, but cut every word that doesn't need to be there.
And most importantly, keep writing!
