Laura Lam returns to the near-future SF world of False Hearts with the speculative thriller Shattered Minds.

Carina used to be one of the best biohackers in Pacifica. But when she worked for Sudice and saw what the company’s experiments on brain recording were doing to their subjects, it disturbed her–especially because she found herself enjoying giving pain and contemplating murder. She quit and soon grew addicted to the drug Zeal, spending most of her waking moments in a horror-filled dream world where she could act out her depraved fantasies without actually hurting anyone.

One of her trips is interrupted by strange flashing images and the brutal murder of a young girl. Even in her drug-addicted state, Carina knows it isn’t anything she created in the Zealscape. On her next trip, she discovers that an old coworker from Sudice, Max, sent her these images before he was killed by the company. Encrypted within the images are the clues to his murder, plus information strong enough to take down the international corporation.

Carina’s next choice will transform herself, San Francisco, and possibly the world itself.
