if youre so certain of your own beliefs- certainly its not a threat to read a book by someone who disagrees? why impose purity tests? why are you afraid of exposing people to ideas that you disagree with?
Try the following - books and articles. As you said "law and legal theory", I understood you to mean you wanted Jurisprudence/legal philosophy readings (apologies, haven't abided by usual bibliographical conventions, just listed stuff which came to my head).
Books:
1. H.L.A. Hart, 'The Concept of Law'.
2. Ronald Dworkin, 'Law's Empire' (maybe also try 'Justice for Hedgehogs').
3. Lon L. Fuller, 'The Morality of Law'.
4. John Finnis, 'Natural Law and Natural Rights'.
5. J. Lear, 'Aristotle: the Desire to Understand'.
Articles:
1. H.L.A. Hart, 'Positivism and the Separation of Law and Morals'.
2. Noam Gur, 'Ronald Dworkin and the Curious Case of the Floodgates Argument'.
3. Kristen Rundle, 'The Impossibility of an Exterminatory Legality'.
*4. Eric Heinze, '*The meta-ethics of law: Book One of Aristotle’s Nicomachean Ethics'.
5. Brian Leiter, 'Legal Realism and Legal Positivism Reconsidered'.
For example, I think 'Justice' by Michael Sandel is a must read.
It's PDF is also available freely on the internet.
