Ava Frost has spent the past three months mourning the death of her brother, Ian, but now she's facing criminal charges from Department 51—charges that could put her in federal prison for the rest of her life unless she accepts their "work-release" deal.

She can hardly stand working for the organization she blames for the death of her brother, yet while on the Department 51 base she makes a chilling discovery...a sentient, complex computer program called Ian 2 has been imprinted with her brother's anagrams. More shocking the program is linked to her brain, sharing the same organic metal as her cybernetic implant.

Department 51 wants her to disable Ian 2, but when an alien craft threatens the Earth, Ava discovers her brother's program may be the only key to deciphering the invaders' intentions. Can she use Ian 2 to stop the alien invasion? Or will she be forced to save herself when a band of supernaturals try to remove her implant and Ian 2 can't reach her?
