While I didn't get the book for this, I have learned more from it about PCB layout than most books I've read: Electromagnetic Compatibility Engineering by Ott.
I go this to make sure I understood what causes and how to prevent EMI in the new high speed board I am working on, so we can get FCC certification. It gave me a real understanding of pitfalls for high speed circuits.
This won't be much help in laying out big power circuits.
