Hard Reboot
features giant mech arena battles and intergalactic diplomacy. When did academia get to be so complicated?
Kas is a junior researcher on a fact-finding mission to old Earth. But when a con-artist tricks her into wagering a large sum of money belonging to her university on the outcome of a manned robot arena battle she becomes drawn into the seedy underworld of old Earth politics and state-sponsored battle-droid prizefights.
Is it time to get back to the books, yet?
