Opal's Brigade (Paperback)

Opal, one of the Lightning Brigade, who lives in the Neath World far below Earth's surface, must break a more than a thousand year pact to travel to The Topsider World in order to protect her twin sister, Sadie Evelyn. Sadie Evelyn, hidden at birth in the Topsider World twelve years ago, has no idea that she doesn't belong in her world. Is Sadie Evelyn the key to the power of Neath World? Or is she the reason for the shift in power? Will the two worlds survive? The Triad and The Trinity, two opposing forces of the Neath World, battle it out for power. Which side should win? Follow Opal's journey as she discovers the Topside World. Figuring out good and evil is not always clear.
