When the Founders' plan to get rid of Seb for good backfires, they form an unlikely alliance with Tara to rescue Seb from eternity in the ghostly village of Hollowfall.

Tara discovers she can save Sorsha and evict the Founders from their human hosts if she can get her couple chosen as Snootcoming King and Queen. But Cam and Sorsha are the only eligible ones, and that would endanger Sorcha's relationship with Seb.

After Seb's kiss with Sebastienne, Sorsha's bond with Seb is broken, and the Founder within her takes control. The Founders are now three, and all-powerful.
