This was a magical story that involved ALL the things I love; design, books, google, geeky tech and even a museum for yarn! I crave books like these and they only come once so often, which made it a great surprise to have two fun reads in a year... the other being "[b:Ready Player One|9969571|Ready Player One|Ernest Cline|http://d.gr-assets.com/books/1333576871s/9969571.jpg|14863741]" by Ernest Cline. Both books give a good feeling mystery with a futuristic twist. I fell in love with Penumbra, his bookstore and wanted to be involved in the search/mystery myself. I love authors that really understand the magic of a good adventure, it's like the lost art of storytelling and we could really do with some more like this. The writing itself is done well, nothing astounding but with a story like this... sometimes you can overlook a bit of youthful "teen lit" writing, especially when done well. I would recommend this to anyone and everyone who loves books, reading, mysteries and futuristic techy books.
