I Am Number Four meets the TV show Fringe in this thrilling, high-stakes sequel to Unraveling.

Four months after Ben returned to his home universe, Janelle believes she'll never see him again. Her world is still devastated, but civilization is slowly rebuilding, and life is resuming some kind of normalcy—until Interverse agent Taylor Barclay shows up, asking for Janelle's help. Somebody from an alternate universe is kidnapping people and selling them on different Earths. And Ben is the prime suspect. When Janelle learns that someone she cares about—someone from her own world—is one of the missing, she knows that she has to help Barclay, regardless of the danger.

Now Janelle has five days to track down the real culprit, locate the missing people before they're lost forever, and reunite with the boy who stole her heart. But as the clues add up, Janelle realizes that she may not know Ben as well as she thought. Can she uncover the truth before everyone she cares about is killed?

In this heart-pounding sequel to Unraveling, author Elizabeth Norris explores the sacrifices we make to save the people we love and the worlds we'll travel to find them.
