My friend showed me this book in the Teksons bookstore, it was so bad i wouldnt have bought it for free. In fact,now i think i should buy it ..as it will help me to sleep better :-)Now i know why it is important for authors to be older ..i mean i respect age now ! The one star i am giving it is because there is no option of 0 stars in it !
