Their nightmares have just begun...

Hell bent on moving into Chuparosa, Thomas has dug up another root from the family tree that Laura and Sarah would rather leave planted in the past. Of course, that's not the only thing complicating life for the Deane sisters.

Sarah's magic has gotten darker since their last battle in the desert and though Drew works hard to keep a suspicious Daniel off her trail, she's working even harder to push him and everyone else away. Without her sister, Laura always seems to be one step behind Thomas and her frustration builds as she learns they could be working together.

Meanwhile, Daniel's latest assignment has exposed the more restless residents of the Other Side and Laura finds herself alone at the center of a plot that could undo everything they started. She longs for a partnership with Sebastian, but his feelings may be clouding his judgment.

Separated and struggling, are Earth's new Defenses going to be ready for what's next?
