A great book for summer reading is "Rust: the longest war".
Cars rusting! Bridges collapsing! Rust, and corrosion in general, is probably the most important topic that is not on most people's radar. This is definitely something people should be paying more attention to.
Other topics include the the patina on the Statue of Liberty, the development of stainless steel, can coatings, publicizing corrosion, oil pipelines, and the future of combating corrosion.
The book is a fairly quick read and is accessible to students and laypersons.
