WANTED: WANTED: "Danger in the Dorm" by Ann Rule

Hello! I love Ann Rule's books and literally own every single one. Or so I thought. I discovered there's one title I don't have and it's "Danger in the Dorm". I am desperately in search for this book. I can only seem to find it in Kindle version so I don't even know if it's in paperback form. It's not a collectors or anything like that, I'm just hoping to complete my set. I don't care how rough of shape the book is in either. Her books used retail for around $5 paperback and $10 hard. I'm willing to pay upwards of those prices depending on the shape of the book. Thanks!! :-)
