'The idea of time travel has been with us since ancient times; now the concept of time travel seems... almost... plausible. Today, tales of chrononauts are more imaginative and thought-provoking than ever before: new views, cutting-edge concepts, radical notions of paradox and possibility—state-of-the-art speculative stories collected from those written in the twenty-first century. Forward to the past, back to the future—get ready for some fascinating trips!'

Mary is time-tripping with Charlie, her tiny automaton partner, and very much enjoying 1923. Although ultimately from the future, their travels have taken them everywhen, to all the most special moments.... But they are there on business, not just time tourists, and their clients pay with a small amount of their time (Lois Tilton, Locus Online).
