The Cambridge Companion to International Law (Cambridge Companions to Law)

It covers a wide range of contemporary international law issues with insightful information. Each chapter is not too long but comprehensive of the relevant background and legal points of view pertinent to the work at hand. However, it would be more useful if a chapter on dispute settlement and on international environmental law could be included in the next edition.

The best book on a complex subject. Different countries have different sets of laws on matters that are important internationally. Tells about laws that are common to all nations.
