Lieutenant Dair mu T'resa heads a squadron of SEAL (surgically enhanced/altered lifeform) pilots responsible for the security of the quadrant containing her home world of Kevarzangia Two. She finds a new calling in life as an interstellar paramedic leading the first Bio Rescue team. But the entire project faces opposition from a lupine species with a hatred for native 'Zangians like Dair...

After driving their mutual enemy out of the Pmoc quadrant, the Allied League of Worlds gather for a peace summit on K-2, the homeworld of the underwater-dwelling 'Zangians. With the Bio Rescue team assigned to protect the delegates, Sub-Lieutenant Burn mu Znora's attention is placed on the daughter of one of the ambassadors, who is hiding a deadly secret-a secret that may alter the fate of four worlds.
