I love the origins of English words. A book on the history of a ton of words would make for ana interesting read.
from the actual "ISBN" titles, without too much of a system but as a preliminary scavenging read you may check:
Justin Cord Hayes - The Unexpected Evolution of Language
and
Nigel Rees - Why Do We Say
(Nigel Rees also being the conductor of the 500 episodes of the radio programme "Quote... Unquote". Very prolific writer, apparently, other titles from him could be relevant).
Also, if you are a member of a public library, you can often get free access to the full Oxford English Dictionary online, which has detailed etymologies.
