This is the blurb:

"Damian Kane thought his life couldn’t get worse. He was wrong.

After being expelled from boarding school on false charges, he is compelled to go to the Antarctic to be with his SAS father, Captain Sebastian Kane. There he meets an impossible alien whose image has appeared frequently in his nightmares. This meeting changes his past, his body, and his life.

He meets an ally, Navigator 9751, a holographic humanoid artificial intelligence from beyond the Solar System. With its aid he manages to escape the threat of the Interceptor, an inhuman alien, Shakespeare-quoting, deadly force. A soldier of The Enemy, the Interceptor is dedicated to its masters’ purpose: consuming all living things in the galaxy.

His body now changing beyond control, in order to save his life Damian is forced to enlist the help of his best friend, fellow student and pianist Bethany Warde. Together with Captain Kane and Navigator 9751, they form the crew of the starship Scout 9751 to fight their unbeatable foe.

If they lose, all life on Earth will be destroyed, and all humanity in the galaxy will perish."
