A mysterious terrorist organisation has carried out several attacks against the Federation and Klingon Empire. Tensions are running high in a region already crippled by conflict. The perpetrators are tracked to the Lembatta Cluster, a mysterious region of space whose inhabitants, the Renao, regard the Alpha Quadrant s powers as little more than conquering tyrants. The Federation are desperate to prevent more bloodshed, and have sent their most powerful warship, the USS Prometheus, into the Cluster to investigate the threat before all-consuming war breaks out.

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!

For years, Starfleet Intelligence agents have carried out undercover assignments deep within the Klingon Empire.

After three of Starfleet’s longest serving agents fear exposure, they initiate emergency extraction procedures.
