??
my GUESS is that the book k map is
= 1,4,7,10,13,14,15 ... but thats not what it says
and your k map is
= 1,4,7,10,11,13,14,15

and that the book is wrong .... and you copied it wrong too ....
i didnt really look in to the boolean side yet

The book is correct. You introduced a term #14 that should not be there.
