I can't help you with that book, it's pretty new (2013), although I think a free kindle version is available from the author's site. (EDIT: Sorry 'bout that - no, it looks like it wasn't legit, and has been removed.)
There are a bunch of other good books on the web if you look hard enough e.g.
Digital Systems Design with FPGAs and CPLDs Ian Grout 2008 Elsevier
Advanced FPGA Design Architecture, Implementation, and Optimization Steve Kilts 2007
Digital VLSI Design with Verilog John Williams 2008
FPGA PROTOTYPING BY VERILOG EXAMPLES Xilinx SpartanTM-3 Version Pong P. Chu 2008
Good hunting.
