The Conquerors Saga Books in Order

After unknown alien ships destroy a human task force, Lord Stewart Cavanaugh believes his son Pheylan has survived in captivity. He recruits a rescue team, defying official claims and security restrictions while humanity confronts a new enemy.

The human-alien conflict unfolds from the Zhirrzh perspective as Searcher Thrr-gilag faces disgrace after a prisoner's escape. Clan politics and personal loyalties complicate his efforts to understand a war whose origins may be different from what his people believe.

Humans and Zhirrzh prepare for an all-out war that could destroy both civilizations. A few people on each side suspect a catastrophic misunderstanding, but hidden interests and entrenched hostility stand between their discoveries and any chance of peace.
