James Goodwin uses his olfactory equivalent of perfect pitch to sniff out people's emotions, from love to malice. He earns a handy living by uncovering corporate cheats, but he's growing bored. When billionaire Garth Cotton asks him to cook up the world's first love potion, James first smells a grand challenge, and accepts. But once on the high seas in Cotton's mega-yacht, James smells treachery. He sniffs out secrets that land him and Cotton's dazzling assistant, Samantha Heartgrave, on a timeline to death. To save himself and Samantha, James must exercise his gift of smell in ways he never dreamed possible.
