Markku Eskelinen has built a great critical monument devoted to the text as a whole and its theoretical study ranging stunningly across literary theory, ludology, ergodism, new media studies and transmediality. His deep knowledge of the subjects that are object of his sharp attention, his intelligence and intellectual brightness, his provocative style and the will to understand and explain how textuality works make Eskelinen the foremost scholar in the field. With connections to all literary media and transtextual relations between them, Cybertext Poetics is a major work of cultural criticism that reminds us of the power of literature. --Laura Borràs, Associate Professor, Comparative Literature and Literary Theory, University of Barcelona, Spain; and Director of the Hermeneia Research Group
