Revenant (Star Trek: Deep Space Nine)

Jadzia Dax has been a friend to Etom Prit, the Trill Trade Commissioner, over two lifetimes. When Etom visits Deep Space Nine with the request to rein in his wayward granddaughter Nemi, Dax can hardly say no. It seems like an easy assignment: visit a resort casino while on shore leave, and then bring her old friend Nemi home. But upon arrival, Dax finds Nemi has changed over the years in terrifying ways…and the pursuit of the truth will plunge Dax headlong into a century’s worth of secrets and lies!
