The Astral Hacker by Brian Terenna

In 2120, New America is the world leader in technology and individual freedom. Why, then, has seventeen-year-old Fae Luna felt like an isolated prisoner her entire life?
She survived the worst of the foster care system by honing her skills as a top-level hacker and thanks to the support of her humanoid robot, Sunny, who is illegally upgraded to a human-level AI.
Finally, she’s matched with a foster mom who treats her kindly. Fae slowly lets her guard down until a suspicious tragedy tears them apart. With no flesh-and-blood friends, she is forced to call Blaze, a guild-mate from her online holo-game, who introduces her to a motley crew of rebels and loyalists. When they dig into Fae’s mystery, they discover a far-reaching and deadly conspiracy.
Fae promised her dying mother she would never alter her body with a brain implant, but with the Evo, her hacking skills would be unbeatable. Lethal battles and devastating consequences will challenge her vow.
Will Fae choose the enhancement or trust her own exceptional mind to defeat a secretive and powerful force threatening all New Americans?
