Jailbird: A Novel by Kurt Vonnegut, for two bucks. This is related to current events:

Jailbird takes us into a fractured and comic, pure Vonnegut world of high crimes and misdemeanors in government—and in the heart. This wry tale follows bumbling bureaucrat Walter F. Starbuck from Harvard to the Nixon White House to the penitentiary as Watergate’s least known co-conspirator. But the humor turns dark when Vonnegut shines his spotlight on the cold hearts and calculated greed of the mighty, giving a razor-sharp edge to an unforgettable portrait of power and politics in our times.

Also, while we are talking about cheap books, Powder Burn by Carl Hiaasen, in case you are a Hiaasen fan. I’ve not read any of his more recent books, and maybe that is because I don’t like them as much as his earlier books, but I don’t want to put down any book I’ve not read.
