For 200 years Justine Bennett has been sole guardian of Desdemona's Temptation (Mona), also known as the key to eternal youth. Originally a jewel-encrusted golden goblet, today Mona is, well, an espresso machine.
Being guardian isn't easy - all forms of evil are after Mona and no one is to be trusted. With all this pressure, it's no wonder Justine has no time for a love life! And now, Derek LaValle, a famous low-carb pretzel mogul, accuses Justine of putting a curse on his family - why else do all his male relatives die at the exact same age?
Derek is desperate to save himself and his twin brother from this tragic fate. When Derek and Justine learn that Satan's disgruntled son, Satan, Jr, has cursed Derek's family, they must join forces to keep Derek alive and protect the Fountain of Youth. Along the way, Justine just might discover that dating IS possible for a guardian.
