I have learned that kore is 'this' so the first line is 'this is a book'. Kono is always used before the known item. So kono hon.
Eg
Kore wa Nan desu ka? - what is this?
Kono hon wa Nan desu ka? - what is this book?
Koko is 'here'.
Think of them as:
Kore, sore, are, as this, that, that over there.
Koko, solo,asoko, as here, there and that place over there.
