“Look to the stars and be grateful!” GiGi tells young Milo and Lizzy.

Guadalupe Luna, who came to be known as GiGi, was Milo’s wise grandmother and guiding force, with whom he and his sister lived for most of their childhoods. Born in a small fishing village on the Yucatan peninsula, GiGi’s family escaped murderous gangs when she was a child, following the constellation “Seven Macaw” northward to California. GiGi’s mother had been a revered Mayan Astrologer, and her notebooks were passed along to GiGi. GiGi was a respected astrologer in her own right, and she enjoyed ascertaining Milo and Lizzy’s friends’Mayan astrological sign, according to the ancient Tzolk’en.
