"Thomas is excellent at assimilating and presenting a digest of the main trends in research while also throwing new light on texts by focusing on a few telling aspects of the works. In 'The Defence of Camelot' he has succeeded in providing a clear overview and a distinct profile of a period which tends to be neglected." (Elizabeth Andersen, Durham University Journal)
