About 15 years ago, I read a book about a classical musician whos wife (possible girlfriend) dies and he turns to writing commercial jingles (which he feels is selling his soul, but is well-paid) to pay for cryogenic suspension until the end of the universe. The premise is that the big bang started expansion, but as the universe contracts, time would go backward and he would be reunited with his wife.
He is woken up in the future and agrees to work for a government or corporation. One of these jobs sees him visit a planet where small conical creatures live, similar size to dogs. The technology allows his thoughts to be placed in to new bodies, and he goes to see the planet, but the small creatures keep attacking and killing him. He keeps going through this cycle, because he told the ships computer not to tell him if anything bad happens to him.
Anybody got any idea of this books title?
