Sharpley’s shorter course for beginners is the most obvious way forward for beginners to continue after his day ‘Latin for Beginners’.
This title is a new edition (2014) of Get Started in Latin (2010) and Teach Yourself Beginner’s Latin (1997/2003).
The longer of the two Sharpley courses. Selections from actual authors present a historical survey of ancient Rome, including chapters on life and society. This course provides a detailed and comprehensive approach to the language, with plenty of practice exercises. Online supports are here.
