So the answer is 17 CM. All the way through Books 2 and 3 (16 CM), and the front cover of Book 1 (0.5 CM) and rear cover of Book 4 (0.5 CM). The bug starts touching Book 1 page 1 and ends touching Book 4 last page, he does not need to eat through those pages to meet the requirements of the puzzler. (Must be a pretty flat bug to take up no space when he starts out.)
