Now the exciting saga of the next generation begins.

First Warning

Khorii, daughter of the near-mythic Acorna and her lifemate, Aari, must contend with an overwhelming legacy to forge a path of her own through a universe filled with new adversaries and adventures.

A simple journey home to visit her parents turns into a race against time when Khorii happens upon a derelict spacecraft drifting in space, its crew dead in their seats. But this gruesome discovery is only a dread harbinger—a deadly plague is spreading across the universe and not even the healing powers of the Linyaari can slow its horrific advance. Khorii, one of the few unaffected by the outbreak, must find the nefarious perpetrators and a cure before the disease consumes all in its path—including her beloved parents.

It is difficult growing up in the shadow of heroes revered throughout the galaxy. But that is the lot of young Khorii—daughter of the legendary Acorna and her lifemate, Aari—who must now follow her own destiny through a fantastic universe of wonders and perils.

Khorii became a hero in her own right as she fought to save the universe from a mysterious, deadly plague that not even the healing powers of the Linyaari could stop.

Now, confined with the rest of the survivors on Paloduro, the home planet of the disease, it seems as if the danger may be fading, and Khorii and her friends may be able to stem the tide of death and disease... until ominous signs indicate that the perpetrators are near and that the epidemic is only beginning. As old enemies reemerge and a shocking family secret is revealed, Khorii must unlock the malevolent mysteries of the deadly pestilence with the aid of her android "brother" before their unknown foes complete their covert mission to cripple the entire star system.

The dramatic conclusion to the breathtaking saga of the children of Acorna and Aari.

Khorii, the rebellious daughter of Acorna, the near-mythic heroine of her people, has tried to follow in her mother's footsteps in this time of plague and terror. But the pressure on the courageous young woman to succeed is tremendous, and the legacy she is expected to fulfill is overwhelming.

The insidious enemy that has ravaged countless known worlds has left Khorii's illustrious parents too weak to oppose it. Now, as the deadly foe prepares to launch its devastating final assault, it falls to Acorna's children—Khorii and her newly discovered sister, Ariin—to halt the brutal attack once and for all. But victory may prove too difficult, elusive, and ultimately fragile—and even time itself may be conspiring against the daughters in their desperate battle to save their family . . . and their universe.
