Sam became a time traveler by accident. But in time: in one of the long-forgotten eras, his father Allan Faulkner was lost. Three amazing objects - an old book, a patterned stone and a coin of unknown origin - opened a door to an arbitrarily distant past for Sam and his cousin Lily.

Having visited Ancient Egypt and the country of the Vikings, at the foot of the erupting Vesuvius and in a shootout in the middle of Chicago, the 14-year-old hero seems to be fed up with such troubles. But one single matter, infinitely important for Sam, remained unfinished: three years ago his mother died, he promised his father to save her. You can go back in time and prevent the accident that took your mother’s life. All it takes is one more correct coin and the Faulkner family will be the same. However, someone wants to stop Sam at any cost...
