Rising Tide, the sequel to Falling Sky, was released on October 6, 2015.
Publisher's Weekly said, "Khanna crafts a terrifyingly dismal picture of the future, raising the stakes by gradually stripping Ben of friends and support while throwing him into increasingly dire situations. His worldbuilding remains solid and unsettling, and he never loses sight of the human element. The cliffhanger ending is sure to leave readers on the edges of their seats, panting for resolution."
