The Guild's Aquarius

By day Charlotte passes as an unassuming MI6 agent; by night she is Aquarius, one of twelve Zodiac assassins employed by the shadow organisation known as The Guild.

Her boyfriend Freddie, an intelligence operative codenamed Relay, stays at her side and in her ear as a hit on an elusive wanted villain becomes a job unlike any other.

The Guild brings in a new pilot, Theo, codenamed Hangman, whose interest in Charlotte goes beyond the mission once he meets Freddie.

Trouble worsens when her meddling MI6 subordinate, Aaron Dixon, grows suspicious and digs into secrets meant to stay buried, putting the operation and her team at risk.

With the clock running and The Guild always watching, Charlotte has to protect the people she cares about.
