Query: A good choice for your _second_ Esperanto book...

This book is divided into four parts. First is an extended essay on the language and the movement, past, present and future--good information for the newcomer. Second is a ten-lesson "basic course" that covers the gramar and hits the high points of usage--the lessons are acceptable, but not outstanding. Third--and the real strength of the book--is an intermediate-level reader of texts, with notes and commentary. Last of all, a word list that makes up a reasonable "my first Esperanto dictionary" before buying, say, the Wells dictionary. There are better choices for a first book on the language--in particular, the Teach Yourself entry--but I think this book is hard to beat for the _second_ book you put on your shelf, to expand your skills and deepen your understanding. That's how I'm using it right now, and I'm quite satisfied.
