Cousins in the Time of Magic — Emma Otheguy

Three cousins get transported back to 1862 to play an important role in the Battle of Puebla, the reason we celebrate Cinco de Mayo today, in this enchanting middle grade fantasy adventure.

History is alive with magic. That's what zany Tía Xia is always telling cousins Jorge, Camila, and Siggy. Daredevil Jorge couldn't be more different than his cousins: Camila is a dreamer who adores animals and Siggy is an aspiring influencer who has an exclusive party to attend. And their aunt has many secrets, including a mysterious diamond-encrusted sword that Jorge definitely wasn't supposed to see.

But when the three stumble upon a time portal in their aunt's yard, they are transported back to 1862, a past filled with wonders -- and dangers. To return to the present, they must race to deliver the sword to General Ignacio Zaragoza in time for the historic Battle of Puebla in Mexico: the foundation of the holiday Cinco de Mayo.

As their journey to Mexico takes them through the Civil Warâ€"era United States, the cousins see just how much US history has been shaped by Latin communities. They must find the power within themselves to make sure things happen as they're supposed to, without altering the past.
