Critically acclaimed author Emma Otheguy joins Newbery Honor-winning
Adam Gidwitz as co-author of the newest adventure in the NYT
bestselling Unicorn Rescue Society series as the kids travel to Cuba to
help the legendary Madre de aguas.
In Cuba, it is believed that a mysterious water serpent--the Madre de
aguas--is responsible for providing and protecting the fresh water of
the island. But the serpent is missing, and a drought has gripped the
island. Uchenna, Elliot, and Professor Fauna fly to Cuba and endeavor to
rescue the Madre de aguas. Unfortunately, it tries to kill them.
Meanwhile, the Schmoke Brothers' goons are driving around Havana,
dumping pink sludge into the sewers. What is going on? Can Elliot and
Uchenna end the drought? Stop the Schmokes? Or will the creature they
are trying to save just eat them instead?
