  'summary': 'Tatja Grimm grew up among stone-age primitives, but she always knew that she was destined for something greater. When she starts working on the fabulous barge that circles her world publishing magazines, she begins to discover how very much she never knew. Exposed to new technology, to reading, to people who have experienced the wider world, she finds wonder in all of it. Rising through the ranks she proves far more special than anyone could have known. Before she is done, the world will know that her intelligence is matched only by her insatiable appetite for more, which makes conquering her world less an end than a beginning.',
