It's all down to Giacomo, and whether he can come up with a brilliant solution. And if he does, will his Master go for it? After all, Leonardo still doesn't seem to trust him. He refuses to teach Giacomo how to paint; he won't help him find his parents; nor will he discuss the significance of the medallion, ring, and cross that Giacomo was carrying when Leonardo found him. But with the secret arrival of a powerful stranger, Giacomo is about to discover much more than the answers he has been looking for. And he will also receive an invitation to help arrange a meeting that could change his life. . . and the future course of history.

With more twists and turns than a spiral staircase, this thriller is as unique as its two heroes -- the most celebrated artist who ever lived, and a young man without a past, who will stop at nothing to find the truth about his life.
