Bia's Blade. A Relic Hunters Novel, #6

Keep your friends close and your enemies closer. Bethany Aodhán is not only a reluctant relic hunter for Deva's Fae Council, but also a major "chess piece" in the latest round of godly games. When a fallen storm goddess tasks her with finding Bia's Blade-a godly weapon capable of bringing anyone under the control of its wielder-she knows danger will once again stalk her. As if that was not enough to deal with, the council hands her a second mission-find the person who, with the help of another godly relic, broke into one of the most secure banks in all of England to steal a handful of documents.
It soon becomes clear that the person behind the break-in is after the same thing Beth is-the location of Carla Wilson, the second-in-command of the Ninkilim. But things become more complicated when she receives confirmation that someone close to her works for the enemy. What she doesn't know is how far they will go to fulfill their contract. And whether it really even matters. Because Carla Wilson has finally had enough of Bethany's interference, and is now determined to bring her under total control.
with the help of Bia's Blade.
