Henry 'Hank' Lehnsherr Cilan Mercury, is the second son of Silas. He was bullied at school as a child because of his glasses and geeky look. But behind those glasses are eyes that see everything. He is a scientific mastermind. He lives in the Emerald Palace with his Uncle Cilan, and cycles through the sky on his JetBike. He does not get on well with his father or brothers, and only finds family with his Uncle and cousin, Carlos. His friendship with Ender has led him to fall deeply (and hopelessly) in love with Robin, Alex's daughter (it will never happen).
