Light on Life is an exposition of methods for the popular audience. A pop-encyclopedia if you will. The book is full of essential information, professionally presented and easy to consult. The interpretations of the authors are a little careless and banal, and they seem to pass on the knowledge well, but their translation work is doubtful. For instance, they characterize Danishta nakshatra as 'rich'. While those with their moon in Danishta are known for their benevolence and an air of abundance, they certainly don't make the Bill Gates of the zodiac. In fact Bepin Behari says this is the sign of beggars or saints.
There is an issue of authenticity which in this genre has become critical. The authors do cite some scripture, but I feel this needs to be more diligently pursued. The 21st century has inherited a rat's nest of culture that cannot be made sense of without looking at the origin of our ideas. There's just too much controversy in Jyotish otherwise. ( )

An important book about Vedic astrology, but better for those who already have some basic knowledge.
