It's great to have a collection of novellas together in paperback to keep together with the rest of the books, even though it is three. All three novellas provide background on certain individuals in The Lorien Legacies and are great leadups to the next books in the series, e.g. novella one for book two, novella two for book three, and novella three for--and I am guessing here--book four, which is out next year.
