This book was a little hard to read because it goes into extreme scientific detail at times. However, definetly worth the effort. I liked the concept of data travelling thru time instead of people, making it seem more realistic than some time-travel stories. Good plot too, with a very good twist I didn't expect.
I enjoyed this book, exploring a little informational time travel paradox. Preserves a sense of wonder throughout the book.
When Murdoch was summoned to his grandfather's isolated Scottish castle, he had no idea of the old man's latest discovery--nor where it would lead him. Sir Charles, a genius in far-out physics, had found a loophole in the law of conservation of energy; in any process an incredibly tiny increment of energy escaped--back through time. Using this 'tau' radiation, he could send messages into the past.
But Murdoch discovered records of messages he knew he had never sent! Were may futures possible? Could a message from Future X alter the past--and thus wipe out Future X? But who would be foolish enough to send a message that could eliminate his own existence?
