Treachery & Danger by Monica La Porta

A Masquerade Ball…A secret gathering of Bloodmates…And an ancient Vampire who wants them dead!
One year has passed since Adrian and Lavinia met in the most tragic of circumstances. What better way to celebrate their happiness than accepting an invitation to a most exclusive party?
Organized by Victor Strong, the gathering will give them a chance to meet other bloodmated couples at a top-secret and highly guarded location. Lavinia is ecstatic at the mere idea of getting to know other couples like them, and Adrian would do anything to make her happy.
The moment they arrive at the clandestine destination, horrifying attacks start, and what should’ve been a relaxing vacation with friends becomes a holiday from hell. Will Adrian and Lavinia remain unscathed? Or will evil prevail?

Please note, Treachery & Danger is a standalone title within A Vampire’s Thirst series.
