--Adam the immortal
Adam has accidentally stumbled upon an important period in history: Vienna in 1814. Mostly, he'd just like to continue to enjoy the local pubs, but that becomes impossible when he meets Anna, an intriguing woman with an unreasonable number of secrets and sharp objects.
Anna is hunting down a man who isn't exactly a man, and if Adam doesn't help her, all of Europe will suffer. If Adam does help, the cost may be his own life. It's not a fantastic set of options. Also, he's probably fallen in love with her, which just complicates everything.
