How can a drug that makes people fall madly in love be a bad thing?

So thinks Professor Bacci when he inadvertently unlocks the biochemical key to falling in love, and develops a drug capable of creating emotions indistinguishable from the real thing.

Determined that the world benefits from his discovery, he seeks funding and business advice from a private Swiss bank, owned by the secretive Kappel family. Unknown to Bacci, however, Helmut Kappel sees love as a sickness to be exploited, and has his own plan for abusing the drug’s power; a cynical nightmare of breathtaking arrogance far removed from Bacci’s naive dream of spreading love around the world. Only two people can stop Kappel’s dark vision. One is Professor Bacci’s daughter Isabella, a doctor dedicated to saving lives. The other is Kappel’s own son and heir, Max, a man raised to feel no emotion and show no pain, a killer apparently incapable of love. But before they confront Kappel they must first confront their feelings for each other. Can love conquer all in a world where even true love can be faked?
