Guanínké The Amulet of Kakata

Perfect for fans of Percy Jackson and the Olympians and The Chronicles of Narnia.

Irene Rosales Vivas is so stoked for summer to start. She daydreams about playing on her gameboy and 123 Pescao with her little brother, Alejandro, and hanging out with friends at the beaches of San Juan. Then her mami packs up the whole family in Papi's car and sets their destination for her estranged abuelo's home in Camuy. Upon meeting her abuelo, she notices how dismissive he is to her mami and how he makes everything about himself, souring her impression of the man.
The last thing Irene expected was to find a huge mirror covered in Taíno markings in his office. When she and Alejandro touch it, a portal bursts to life. And to make things worse, her abuelo pushes them both through it, thrusting them into a world of magic, monsters, and where the gods are as real as you and me.
Speaking of gods, on Irene and Alejandro's arrival, she accidentally cuts her hand on a statue which awakens an ancient Cacica, a warmongering chieftain whose magic was so powerful she had to be sealed away in stone. Now the gods have tasked them with the responsibility of finding and destroying the Cacica's amulet, the item that allows her to summon and control hupías, bad spirits which wreak havoc on the living. Sounds easy, right? Irene and Alejandro hoped so. Otherwise, the Cacica's first order of business would be sacrificing them to restore their abuelo to his prime so he can stand at her side and conquer everything in their path.
