The Order of the Banshee

It's been five years since Yael and Molina reunited. Yael is one of the richest and most infamous thieves in the universe and a member of the Order of the Banshee. She is rising through the ranks of the elite organization with her wife and her ride-or-die best friends, Aarif and P'Ken, at her side, and she's even running her own school for thieves. Molina, former captain in the universe's premiere peacekeeping organization, the Sunrisers, is happily married to Yael and tells herself that's enough.
Their seemingly perfect lives are interrupted when they receive news of the death of Molina's father. When Molina returns home for his funeral, she reunites with her former friend and now enemy: Kaybell, the emperor of the Cykebian Empire. Kaybell, eager to mend the relationship, informs Molina that her father was murdered and offers to help Molina find those responsible and bring them to justice.
While Molina and Kaybell hunt the people responsible for her father's death, Yael is hunted by an invincible assassin - one with a terrible secret. These two seemingly unrelated events are more connected than Yael or Molina could possibly imagine.
