Peter J. Ashenden: "Digital Design - An Embedded Systems Approach Using VHDL"
Volnei A. Pedroni: "Finite State Machines in Hardware - Theory and Design (with VHDL and SystemVerilog"
and as supporting material:
Doulos: "VHDL Golden Refernce Guide"

PS: I also have written a book on FPGA and VHDL together with a colleague. But unfortunately this book is in German therefore I woldn't recommend it here ;-)
My recommended books / sites / other material for learning VHDL and FPGA programming are:
Book: Circuit Design and Simulation with VHDL (The MIT Press) second edition (https://www.amazon.com/Circuit-Design-Simulation-VHDL-Press/dp/0262014335/?pldnSite=1)
Book:
The Designer's Guide to VHDL, Third Edition (Systems on Silicon) 3rd Edition (https://www.amazon.com/Designers-Guide-Third-Systems-Silicon/dp/0120887851/?pldnSite=1)
Book: 100 Power Tips For FPGA Designers (https://www.amazon.com/100-Power-Tips-FPGA-Designers/dp/1461186293/?pldnSite=1)
I would recommend the following books from Pong P. Chu: "RTL Hardware Design using VHDL - Coding for Efficiency, Portability, and Scalability", and "FPGA Prototyping by VHDL examples - Silinx Spartan 3 version".
