hmm first answer was wrong, but with help from Nikhil Eshvar things got better.
First you must take a look
probably C - solved by Nikhil Eshvar (C=see) (old answer ?first letter i (sounds like eye))
Next you can eat or cook
next letter p ? (sounds like pea - vegetable to eat raw or cook and eat)
Then half the way around
rotate p by 180 degrees to get d ? or could by half circle.. u? (or U turn!) (old answer ? C is half a circle and it is also rot13(p) (halfway around the alphabet) )
You'll find me in a book!
CPD or CPU -- maybe CPU in a macbookn or notebook ? ( old answer IPC google search brought up Inidian Penal Code in a book, but that sounds wrong.)
