Amp by Sybur Phyre

Earth has lost its battle against the Solcrue, even with the help of their finest creations: CyberTitans. The last of the human resistance is counting on Cara to rescue one specific unit: a Relic.

Amp can communicate with others throughout the galaxy with access to the galactic network tower on Hyperion. If he succeeds, there might just be hope for the rebellion. What he and Cara don’t count on is the desire between them. Humans are not allowed to love machines.

Cara: I’m just a secretary for the rebellion, not a soldier like my father or a cybersystems designer like my mother. I’m not cut out for performing jailbreaks, and definitely not of a mysterious, monster CyberTitan as the hacker model Amp. But he’s the earthlings’ only hope, and I want revenge.
