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

The Sealers have activated Nexus Tear. Lucienne Lam, born to rule as the last of the Sirens, must destroy the ancient weapon before it terminates her. But Prince Vladimir, her first love and once 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.
