I'm a reader, not a writer. Reading is my escape from the stress and problems from my life! I love to express my reaction and emotions to the stories in the comments, as I read along. 
Sometimes, I may give constructive criticism, but it is up to you to take or ignore it. I always leave a review on the last chapter of the books I have read. Warning: That comment might have some spoilers, just in case u have not read the book yet. If I really enjoyed the book, I'll include it in my Reading List. Finally, I prefer to read completed books only.
