This story continues from where Revealed, by Margaret Peterson Haddix , left off. After the whole issue with Charles Lindbergh is solved, Jonah's life has been turned upside down. He barely is getting along with his new brother, their family is being split apart from the boys fighting, and there is an Elucidator lying around their house without JB knowing. On top of all that, Jonah and his friends feel that their last time travel adventure wasn't complete. In other words, they need to save Baby Lindbergh's fate. Almost all of the characters belong to Margaret Peterson Haddix.
