From publisher blurb:
At 0257 Greenwich Mean Time, the Psi-Watch orbital station blasted a Blooded Ghost schooner out of space. Unknown to Psi-Watch, the vessel "Menagerie of Lilith's Teeth" was a bioweapons development vessel, carrying a load of new plagues intended for use against the Blooded Ghosts' Culture enemies here on Earth.
The Menagerie of Lilith's Teeth survived reentry mostly intact. The aft hold held together through the burn and impacted a few miles outside St. Paul, MN. A Psi-Watch xeno-recovery and emergency response team was teleported down to the crash site at 0304 GMT.
Contact with the xenohazard team was lost at 0322 GMT.
All contact with St. Paul was lost at 0418 GMT.
According to Bradbury Station's watchfloor, the last infrared signatures denoting living human beings vanished from Minnesota at 1117 GMT.
Vector of Infection presents a horrifying new reality for Psi-Watch's heroes and villains. An alien bio-weapon kills and transforms superhumans into mutated, merciless killing machines, while ordinary humans die in their thousands, returning to a semblance of life as brain-damaged and voracious cannibal berserkers. Whatever was in the Menagerie's hold may herald the end of sentient life on Earth and it may transform a super-espionage campaign into a nightmarish fight for survival.
