Sundered Moon - Mechanized Hearts, #1

The galaxy is a dark and deadly place, run by vicious corporate empires. Only Central, a nation that rose three hundred years ago after violent insurrection, remains as a beacon of hope and equity to all who reside in their borders. Dia, a young mech pilot from Central, has infiltrated the upper echelons of the Fomorian Armory, an empire that prides themselves on their exceptional pilots and otherworldly weapons.
It's a dangerous game she must play-bringing down an empire-especially after becoming an unlikely ally with the imperial princess, a woman hellbent on gaining her own freedom. Fates will intertwine in this fast-paced mecha romance!
