Isaac Wolf can travel through time. But he's also in a race against
it.
With tensions in Prague rising at the height of World War II, Isaac Wolf
is forced to leave home with nothing more than a small backpack and a
pendant in the shape of an eternity knot. His parents believe the
pendant will keep him safe--if he can discover what it really means.
This clue leads him to Rookskill Castle, home of the Special Alternative
Intelligence Unit where gifted children can learn to harness their
powers to support the Allies' cause. With the help of his new friends
and an antique watch that allows him to travel through time, Isaac must
unlock his own powers and uncover the true meaning of the eternity knot.
The only way he can do that, though, is by hunting for a series of
magical artifacts that are scattered throughout the past . . . and Isaac
isn't the only artifact hunter. Soon he finds himself in a race against
a threat just as deadly as the war itself--one that his parents had been
trying to shield him from all along.
