NEW! The cataclysmic ending to the Blackwater Pond series… In the third and final book of the Blackwater Pond series, The Heart of the Swarm, a broken hearted, Cassie breaks it off with Brian and retreats back into the other world. Determined to get her back, an impulsive Brian recklessly chases into Aphelion Chiasm after her. What was intended to be a quick grab-and-run quickly spirals out of control into the most challenging web of terror yet. He must join forces with old combatants to have any chance to defeat the ultimate evil once and for all or lose everything he holds dear. The balance of power is so fragile that even the actions of one unlikely moth could be enough to tip the scales toward life or death.
