As the students of H.I.V.E. face the challenges of their final year at the school, Otto Malpense is forced to confront his own legacy as a new threat rises from the shadows of his past.

Nothing will ever be the same again as Otto races against the clock to rescue his friends from a rival organization. But as Otto desperately fights for his friends' lives, he ends up facing a deadly enemy more dangerous and powerful than any he's faced ever before--an enemy who's a twisted product of his own bloodline.

From Italy to Russia to the United States, Bloodline is a real tour de force, and a fitting conclusion to the acclaimed H.I.V.E series.
