This is an impressive, meticulously-researched and thorough text. Alongside providing a comprehensive guide to relevant statutes and case law... the book is embedded in the penological research literature and thus avoids being a narrowly-legalistic guide to the law and, instead, engages the reader in both understanding the relevant law and also its socio-legal and penological context. The book manages to combine highly-detailed scholarship with clarity of written expression and a thoughtful and critical approach. The breadth of scholarship, depth of analysis and thoughtful critique of the current law make this book an outstanding addition to the existing published literature. Overall, this is a highly significant text which addresses a complex topic and which should be essential reading for anyone interested in human rights, law, prisons and prisoners' families.
