Nexus Tear (Laments of Angels & Dark Chemistry, #2

The Sealers have activated an ancient weapon Nexus Tear. Lucienne Lam, born to rule as the last of the Sirens, must destroy it before it kills her. But Prince Vladimir, her first love and strongest ally, has joined forces with her enemies over the one kiss she shared with Ashburn Fury--the kiss that is denied to him by the Siren curse.
