The first in a middle grade fantasy duology about a Cuban American girl who discovers that she’s one of the nine Muses of Greek mythology. Callie Martinez-Silva didn’t mean to turn her best friend into a pop star. But when a simple pep talk leads to miraculous results, Callie learns she’s the newest muse of epic poetry, one of the nine Muses of Greek mythology tasked with protecting humanity’s fate in secret. Whisked away to Muse Headquarters, she joins three recruits her age, who call themselves the Muse Squad. Together, the junior muses are tasked with using their magic to inspire and empower—not an easy feat when you’re eleven and still figuring out the goddess within. When their first assignment turns out to be Callie’s exceptionally nerdy classmate, Maya Rivero, the squad comes to Miami to stay with Callie and her Cuban family. There, they discover that Maya doesn’t just need inspiration, she needs saving from vicious Sirens out to unleash a curse that will corrupt her destiny. As chaos erupts, will the Muse Squad be able to master their newfound powers in time to thwart the Cassandra Curse . . . or will it undo them all?

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 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 follow orders and find the tenth muse or trust that sometimes fate has other plans.
