Legion Worlds (Legion Worlds #2)

Ayla Ranzz, the former Legionnaire known as Spark, returns to her home world Winath. Because the planet is populated by twins, Ayla's "solo" status - ever since her twin brother became one of the Legion Lost - makes her something of an outcast. Even worse, Winath's crops are being destroyed by freak electrical storms and twisters, and the person responsible for the damage may tie in with the return of another one of Ayla's family members.
