Sophie Briggs has made it to her junior year at the School of Roots and Vines, but it isn't all fun and games for the Defenders.



Change is coming. Some good and some . . . not so much. Friends are breaking up—will Sophie have to take sides?



Sophie and Marcus are struggling, too. Marcus is pushing Sophie and the rest of the gang away, worried that being a Templeton will put them all at risk. He thinks he needs to do this by himself.



Does he have to go it alone?



Both Sophie and Marcus have taken on jobs at the EBI, unbeknownst to each other, hoping to help mend a bruised heart. Fate might just have a different plan in store for them.



Something dark is brewing again in Mammoth Cave. We're pretty sure it's going to take more than Marcus to put an end to it.



Can Sophie convince Marcus and the rest of the Defenders that they are better together so they can prevent another disaster?
