Verilog Quickstart : A Practical Guide to Stimulation and Synthesis in Verilog (The Kluwer International Series in Engineering and Computer Science Vol.667) (3rd ed. Pr. 2005. 384 p.)

From a review of the Second Edition
'If you are new to the field and want to know what "all this Verilog stuff is about," you've found the golden goose. Though not as detailed as the Verilog reference guides from Cadence, it likewise doesn't suffer from the excessive abstractness those make you wade through.
