Revenant. Starways, #4

Nia Courant is an interstellar lawyer. Her uncle, Val Savre, went missing under questionable circumstances. Now he's turned up again with some major problems. There's a hole in his memory-he doesn't know where he's been and what he's been doing for the past four years. Whatever it was has put him in the crosshairs of the Faxen Union's secret intelligence agency, SECINTAG. And because he was believed to have died, his heirs and unscrupulous others are angling for his intellectual property.  Nia's Uncle Val really needs an interstellar lawyer.
