Fennel and Peree are finally together and safe from the Scourge in the protected village of Koolkuna. But, on the day of their partnering ceremony, the children of the village are stolen away--Fenn's loyal companion, Kora, among them.

Fenn wants to bring the children home, especially as the villagers seem to blame Peree and her for the tragedy. Only, since the death of her own family, she's terrified a wrong move on her part will lead to the loss of others she loves.

Fenn and Peree join a small search party led by rival Kaiya, the one person who stands a chance of finding the children, thanks to her mysterious past. As they travel away from the safe waters of Koolkuna and into the Scourge-infested wilds, Fenn endures Kai's scorn, her subtle designs on Peree, and the squabbling of the group. But, nothing in her life so far has prepared her for the fierce warrior women who will steal others' children to preserve their own existence--the Fire Sisters.

If Fenn is to survive the threat of the Scourge, rescue the children from the Sisters, and have a hope of making a life with Peree in Koolkuna, she must face her fear of failure and loss and become the leader she's destined to be.

The Fire Sisters is the final book in the bestselling Brilliant Darkness series. Three novels and two short stories complete series.
