Xenocide / Card, Orson Scott

Gloriously Bright, the most brilliant analytical mind in a world of people bred for superintelligence, is sent to solve the mystery of the disappearance of a fleet dispatched by the Starways Congress to destroy all life on Lusitania--including humans, pequininos, and the Hive Queen--in order to keep a deadly virus from getting off the planet.

Afraid that the descolada--the deadly virus that the pequininos require to transform themselves into adults--may escape the confines of Lusitania, the Starways Congress orders the destruction of the entire planet.

The Starways Congress decides that the deadly virus on Lusitania must be wiped out and sends a fleet to destroy it. After the fleet disappears, Gloriously Bright is selected to solve the mystery.
