When calculating power and sample size for a clinical trial, I use two sources, Cohen's treatise on Statistical Power Analysis and this text. Sample Size Calculations in Clinical Research structure begins with more common study designs to the more complicated and difficult. The explanations are concise, understandable, and are fully supported by the examples provided by the authors.

Great book!
