The Magic Finger by Roald Dahl was a really quick read. I think I must have finished it in about 10 minutes. It was cute though, and I really adore Quentin Blake's illustrations.
I'm now on The Witches, another Roald Dahl book I haven't read before. One chapter into the book and I find the story rather familiar. I vaguely remember; when I was about 8 or so, I watched a movie about witches having purple eyes and them turning into ugly, wrinkly rats at the end... So I did a check online and indeed, it's an adaptation of Roald Dahl's The Witches! You can read about it here.
Keeping my favourites for the last - Charlie And The Chocolate Factory and The BFG!
