Matter is a science fiction novel from Iain M. Banks set in his Culture universe.
The main character in Matter is a woman who is essentially abducted by aliens (even if she does come to appreciate it) and disappears, only to return years later.
Jim Sullivan wrote one amazing – and as it turns out oddly predictive – record, and then disappeared while traveling from CA to TN.
He reportedly walked into the desert, and was never seen again.
Jim Sullivan's one record? U.F.O.
He seems to have managed the abduction part. Perhaps he will manage the return, as well.
