It is a wonderful book and leaves you on a cliffhanger for the ending, which is terrific. If you have not already read her first book, Shiver, please do. When Linger does hit the sales table, I would recommend geting it to anyone.
It is a book more for the ages of 10-18 or so, but anyone can read it. It is a terrific read with suspense that keeps you reading until the very end.
