It only takes two weeks for me to regret my decision to accompany my aunt on her quest for the lost city of Atlantis. I’m clearly in the minority, though, as my familiar is having the time of her life—well, in between complaining about the size of our room and the subpar buffet options. But no one is happy when the quest takes a deadly turn, and we uncover a secret society determined to keep their patron goddesses’s secrets, even if it means sending us to a watery grave. Selene and Cora’s adventures in Winterspell come to a close in this high-seas adventure.
