Angry Byrd (The Clan Gonther Cycle Book 5)

Brotherly love is strong. But is the drive to power even stronger?

Robert and Tim have come a long way together. Once they were frightened children taken hostage by aliens; now they're Co-Regents of a failing Empire. Confronted by challenges far exceeding any known by their predecessors, the fallible and all-too-human twins must make all the really difficult choices their antecedents lacked the courage to face. Can they set their personal rivalries aside long enough to do so?

The fates of entire sentient races, including all of humanity, hang in the balance.
