This is a clearly written and well-organized textbook by Drake and Singh, treating elementary (albeit axiomatic) set theory for students having some familiarity with naive set theory and elementary logic. The book is demanding but clear. A good background would be provided by reading Halmos's NST and the first few chapters of ML by Ebbinghaus et al. The topics treated here are well-chosen, and even exciting "modern" developments are glimpsed -- such as forcing, boolean-valued models, large cardinals etc.

In short, this is a very good textbook suitable as an introduction to set theory for mathematics students.
