I am serious.Everytime I opened the book I scratch my face and hands. I have never allergic to any book before. When I close the book I feel better until next time I open it. I have seen my family doctor and take some medicine. I am pretty sure I allergic to HF serious books.It is so sad there is no ebook for it and the book is quite good one. What kind of ink does it use? and is there anybody has the same symptom?
