Blackstone Towers by Ashley Lister
The talismans of the magi control seven realms of the mortal world. One can grant the bearer immortality; another gives its owner unfathomable wealth; a third gives the holder unerring foresight. There is a talisman to control reality, success, the deliberate and the accidental, and a talisman that governs the balance between love and hate. The planets are now aligning, and one worldly resident of Blackstone Towers knows the talismans urgently need collecting and destroying before they fall into the wrong hands. The only problem is establishing whose hands are the wrong ones.
