First law of contract, always read the small print. A previous reviewer has given it one star because it's claimed amazon hasn't listed what version this is. Well they have if you read it! It states it is the 29th edition, the 30th is out now. The price represents a saving on the new edition but very much a book for those with some legal knowledge. Not recoomended for those who want to dip their toes in the water, but for those who do deal with contract law on a regular basis , it's a fine piece of work.
