The type of engineering doesn't matter. It may be electrical, mechanical, biomedical, computer, literally anything.
"Engineering is the purposeful use of science" - a quote I heard somewhere and have forgot who said it.
Name some books that made you a better engineer. The books need not necessarily be from your field. You may have drawn inspiration from a related or a non-related subject. E.g.: learning some form of mathematics may make you a better programmer.
Also mention a line of two about why the book has a special place for you.
