Bloodstone

Are you afraid of the dark?' asked the spectre. 'You should be. Everyone would be afraid if they knew what lived there.'

Life has changed dramatically for India Bentley since discovering Ironheart a year ago. Instead of scraping out a living in London, she's been travelling the world, learning to tech-hunt and doing her best to stay out of trouble. Unfortunately, trouble has a habit of finding her.

Falsely accused of an assassination attempt, India is on the run with her mentor, Verity Brown, and scientist Professor Moon: a man obsessed with finding an ancient artefact known as the Bloodstone, the key to a source of unlimited energy, which he believes can be found in the lost city of Atlantis.

Pursued by the ghosts of her past, India must be prepared to risk everything to save her friends . . . and the world.
