Ban Bridget, one of the Hounds in the service of the League, mysteriously disappears, leaving behind a strange note.

Enlisting the help of Donovan, a scarred man who once knew and loved Ban Bridget, Méarana sets out on a journey through the Spiral Arm in her mother's footsteps.

However, Donovan, who himself was once an agent and suffered severely in the process, is skeptical. He understands: something very serious had to happen if it made Bridget's ban disappear, and touching such a secret is very, very dangerous...
