What Happened To Tawnee Stone?

Mondadori I bought a lot of curiosity, 6 children's books really fantastic! The first 5 volumes
I was fascinated by the detailed graphics, the fantasy of the story and the detailed description of the characters that are part of this adventure as experienced by three brothers Grace.
The authors of these books are Tony DiTerlizzi, with regard to the incredible fantasy illustrations (his site: www.diterlizzi.com) and Holly Black for the wonderful short stories (his site: www.blackholly.com).
I'm not a reader of children's books but this collection is beautiful and original in terms of their structure.
The pages are yellowed, the character in the book, changing several times, every few pages there are some wonderful illustrations, references to the mysterious events that occurred previously represented by newspaper articles, some old maps that make it unique reading.
The five books are about the adventures of three brothers dealing with goblins, evil creatures, trolls, magic stones, boggart and elves hiding in the old house the family inherited from a distant great-aunt Grace, all in search of the book In the sixth book of secrets
, just come out, they are all drawings of fantasy characters that populate the first five volumes and, in my opinion, are the most beautiful fantasy art I've ever seen so far!
