I think you should choose books written in more simple English first. If you have to find in the dictionary to understand the story, you will lost interest very soon. It's my experience.
Find books not too thick and words printed in bigger size, those usually for young adults, which should be easier to understand. Actually, Harry Potter is a very difficult book to read if you are a elementary reader. The author 玩弄文字. She is a good writer but the English is too complicated for me, I suppose.
I am a bit crazy last night, I finished the book "Death on the Nile" in 4 hours i.e. till 3:00 in the morning. I was too anxious of knowing who is the murderer and how the murder worked out.
I have got "The Otherland" on hand, but I have to finish 2 more books before starting.
I have bought "The Living History - Hillary Clinton" but it is still in its packing. Does any of you read it?
I am now reading "Four Corners: Into the Heart of New Guinea-One Woman's Solo Journey
by Kira Salak". Just started a few pages. I borrowed this from the public library by chance I saw it was a new book on the shelf. After then, I search information from amazon.com and this novel sounds quite interesting.
( NO NEED TO BOTHER NOW! I just have time to read through a few pages here, and found that I am interested in James Patterson & Dan Brown. I will read these first. Thank you.)
