Milena Minkova's INTRODUCTION TO LATIN PROSE COMPOSITION is a brief handbook to the general principles of writing in that language. Besides covering the basics of sentence construction, Minkova even give examples of the vaster rhetorical tricks employed by various classical writers. Examples abound for each point, though sadly they are not cited.
While none of the information inside is exactly wrong, the book will probably prove unusable to most interested readers. There are no exercises, so students can't gradually build up their skills chapter by chapter. The production of the book is amateur, with poor typesetting and limited editing. If you actually want to learn to actively write in Latin, the standard textbook remains BRADLEY'S ARNOLD LATIN PROSE COMPOSITION, which in spite of its age is extremely rigorous, getting you on the path to comfortable expression in Latin in no time.
