The Wells Bequest by Polly Shulman

So years ago I read this book called The Grimm Legacy by Polly Shulman and loved it.  It was about a magical library (The New York Circulating Material Repository) that lends out objects instead of books.  In the story, some of the items from the special Grimm selection (like the fairy tales...magic mirrors, wands, etc) go missing and the library pages have to find them and save one of their own.  Polly Shulman has now given us a companion book to this.  It's not so much the second one in the series because you can read each one as a stand alone book.  This time the book focuses on the collection in the Repository that contains items from science fiction books like the time machine from the H.G. Wells' novel The Time Machine.  I liked the adventure/time travel in this book and the new characters we get to meet as well as all the references to classic sci fi books.  I just LOVE the idea of a magical library and am hoping this author writes about other collections.
