As an enforcer, Lin is sworn to protect the corporations that rule Earth. But when her people need her help, she’ll have to break every rule to save them.

Yang Lin is a rising star at Hauser Incorporated, one of the three corporations that govern Earth. But Lin has a secret that could destroy everything she’s worked to achieve. She wasn’t born on Earth, but on a refugee ship fleeing a faraway colony. Lin has lived her whole life in two worlds, associating with other refugees from the colonies at home but passing as a successful Earth-born woman at work and school.

Now Lin has to choose.

Her mother and a group of fellow colonists have a plan to get more refugees past the deadly defenses guarding Earth, and they need Lin’s help. Joining the cause could mean losing everything—even her life. Refusing to help will mean the death of thousands from her homeworld.

Meanwhile, unbeknownst to Lin, someone powerful is about to blow her cover. In Insider, a gripping sci-fi thriller, Lin’s next move could save thousands—or doom them all.
