Books that I recommend:
@book{Kahng2011,
Address = {New York, {NY}},
Author = {Kahng, Andrew B. and Lienig, Jens and Markov, Igor L. and Hu, Jin},
Publisher = {Springer Science+Business Media, {B.V.}},
Title = {{VLSI} Physical Design: From Graph Partitioning to Timing Closure},
Year = {2011}}
@book{Alpert2009,
Address = {Boca Raton, {FL}},
Author = {Alpert, Charles J. and Mehta, Dinesh P. and Sapatnekar, Sachin S.},
Publisher = {{CRC} Press},
Title = {Handbook of Algorithms for Physical Design Automation},
Year = {2009}}
"Alpert2009" (LaTeX reference key) is an awesome book. However, it may be too advance for beginners, especially if they have no adequate experiences in digital VLSI design (from RTL to layout) or appropriate background in computer science and mathematics for EE majors/graduates.
Here are general EDA books that also covers topics in physical design.
@book{Wang2009,
Address = {Burlington, {MA}},
Author = {Wang, Laung-Terng and Chang, Yao-Wen and Cheng, Kwang-Ting (Tim)},
Publisher = {Morgan Kaufmann},
Series = {Morgan Kaufmann Series in Systems on Silicon},
Title = {Electronic Design Automation: Synthesis, Verification, and Test},
Year = {2009}}
@book{Scheffer2006a,
Address = {Boca Raton, {FL}},

Some classic old books.

P/S: Ask any Ph.D. student working on physical design for recommendations, especially those who are close to defending their thesis, or about to take or just took their Ph.D. qualifying exam.
