The seeing stone:

"The Seeing Stone" is the sequel to The Field Guide (The Spiderwick Chronicles, Book 1) and is the second book in "The Spiderwick Chronicles" series and for the most part it is pretty good fun. Children will love the fantasy elements of the goblins, trolls, fairies, griffins, etc. especially the rhyming Thimbletack. The Seeing Stone (which helps them see the Goblins) is a nice addition to the series and authors Tony DiTerlizzi and Holly Black invent a funny if somewhat gross way for the children to see the goblins without the seeing stone. What kept me from entirely enjoying the book is that I felt some of the scarier moments were a bit too scary for young children. I found the goblins especially bothersome with their cages full of kidnap victims. And the hint of what might have happened to Simon's cat may be traumatic for younger children.
