"Cod" by Mark Kurlansky is an excellent book. Its the history of the New England codfishery, starting with the Portuguese in the 1400's. It sounds dry, but its not, its fascinating.
"Giant Bluefin" by Douglas Whynott is another great read. It follows the Bluefin fishery, mostly from the point of view of a harpoon boat captain. In fact, after you read it, you'll understand my screen name.
Get better, and I hope these suggestions help to pass the time.
