The finale of an action-packed middle grade fantasy duology about a young Cuban American girl who discovers that she’s one of the nine muses of Greek mythology. Perfect for fans of The Serpent’s Secret, the Aru Shah series, and the Percy Jackson and the Olympians series.

Callie Martinez-Silva is finally getting the hang of this whole goddess within thing. Six months after learning she was one of the nine muses of ancient myth, she and the other junior muses are ready for new adventures. Except first Callie has to go to New York City for the summer to visit her dad, stepmom, and new baby brother.

Then the muses get startling news: an unprecedented tenth muse has been awakened somewhere in Queens, putting Callie in the perfect position to help find her. And she’ll have help–thanks to a runaway mold problem in London, Muse Headquarters is moving to the New York Hall of Science.

But balancing missions and family-mandated arts camp proves difficult for Callie, especially once mysterious messages from spiders (yikes!) begin to weave a tale of ancient injustice involving Callie’s campmate Ari.

Now Callie and her friends have to make a choice: follow orders and find the tenth muse or trust that sometimes fate has other plans.
