Hidden aboard the USS Enterprise is a secret that has been passed from captain to captain, from Robert April to Christopher Pike to James T. Kirk. Now the return of the enigmatic woman once known as Number One has brought that secret to light, and Kirk and his crew must risk everything to finish a mission that began with April so many years ago.

The final frontier erupts into chaos as vast quantities of a rare energy source are discovered beneath the surface of Baldur-3, a remote planet beyond the outer fringes of Federation space. Now, an old-fashioned “gold rush” is underway as a flood of would-be prospectors, from countless worlds and species, races toward the planet to stake their claim. Captain James T. Kirk and the crew of the Starship Enterprise are dispatched to deal with the escalating crisis...which lies on the other side of a famously perilous region of space known as the Antares Maelstrom.

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 Klingon commander Kruge died in combat against James T. Kirk on the Genesis planet back in 2285, he left behind a powerful house in disarray - and a series of ticking time bombs: the Phantom Wing, a secret squadron of advanced Birds-of-Prey; a cabal of loyal officers intent on securing his heritage; and young Korgh, his thwarted would-be heir, willing to wait a Klingon lifetime to enact his vengeance.

For years, Starfleet Intelligence agents have carried out undercover assignments deep within the Klingon Empire. Surgically altered and rigorously trained in Klingon culture, they operate in plain sight and without any direct support, while collecting information and infiltrating the highest levels of imperial power. Their actions have given Starfleet valuable insight into the inner workings of Klingon government and its relentless military apparatus. After three of Starfleet’s longest serving agents fear exposure, they initiate emergency extraction procedures.
