At age 11 Marta was sold by her Uncle Roberto to the Nuevo Leon Cartel.  Rescued by Jacinda Cross and Enrique Salguero during a Quetzalcoatlus hunt, she then was taken in by Enrique.  Mistaking Enrique's kindness for a trick to eventually hurt her, Marta lived in fear for a long time after being taken in by him.  Shortly after her arrival, her Uncle Roberto came to claim her again, Enrique stopped this with the help of a woman named Camila (who was the first person Marta had begun to open up to). After this , Enrique continued to show her kindness as he took care of her, got her started with online learning for school, took her to the zoo, and helping her discover her love for guns. On her 12th birthday, she realized that Enrique truly cared for her, and her healing began.

The pair would later move to Moscow after Marta's adoption was completed.  After arriving, Enrique took Marta on a trip to learn how to hunt with a bow (she had asked to do so).  She began to look consistently to the east and spoke of the wolves talking to her.   Enrique knew that she was a wolfkin.  He would meet two others while there, Sierra Lupita and Elyse Andersen, who would move in with him and help train Marta in the basics of her wolf abilities.  Her eyes would eventually turn gold, and she would begin wearing color contacts to blend in (despite liking her eye color better now).   Both women have since moved out, but Elyse still keeps in contact with the pair.  Marta also has a wolf companion named Spashes Like a Fish (Splash). The wolves have named her Windsong.

Marta's short time with the Nuevo Leon cartel was enough for her to develop PTSD, and she sees a counselor weekly to help with this.  Enrique has remained supportive and has Marta's trust.  She has made a significant amount of progress.  Most days are good ones now, and she has begun to socialize more with kids her age, even getting to the point where she goes to a physical school.
