Children of the Empire — Lara Nance

Ten years ago, Emperor TaSherion and his wife were murdered by a traitor. Their five children were taken by loyal friends and scattered across the galaxy, their memories wiped to protect them. Parts of their father's plan for an unfinished secret weapon have been microchipped and implanted in each sibling. An invasion by the reptilian Crogians sets into motion a series of events that forces one of the children to regain her knowledge of the past. Min, working as a lowly servant in a space-gladiator complex, escapes the attack with one of the gladiators named Ruffian, and together they race across space hunting down her remaining siblings. Now, it's up to these children of the empire to restore their father's secret weapon, and lead the rebellion before the Crogians complete their evil plan to destroy humanity
