Like the other three books of this series, the Citadel is a gorgeously written account of Severian the Torturer's journey to the Autarch's throne in a far future. Gene Wolfe's story is outstanding, if only for the fabulous otherworldly reality he has fashioned with beautiful language and a singular voice. The Urth he has created is real, filled with layered depth and detail. The story reaches a satisfying endpoint in this volume -- I hesitate to call it a conclusion, because like a real history, it could continue forever. This series is one of the best of all time.
Understanding Language Testing presents an introduction to language tests and the process of test development that starts at the very beginning. Assuming no knowledge of the field, the book promotes a practical understanding of language testing using examples from a variety of languages.
