When Matt Hendrick’s wife Mercury is lost while taking a Telemass trip from Mars to Earth, existing in a state neither dead nor alive—but in an ‘indeterminate state’—he finds himself in an indeterminate state himself, torn between grief and hope. Hendrick had planned to take Mercury and his daughter Samantha on a trip to distant stars, retracing the journey he had made years earlier while attempting to rescue Samantha . . . In a bid to distract Hendrick, Samantha persuades him to make the journey anyway, and they embark on a fateful recapitulation of the original voyage. But unbeknownst to Hendrick, Samantha has an agenda of her own—which just might bring about Mercury's salvation. Telemass Coda is the moving finale to the Telemass Quartet.
