Christina Sunley was born in New York City, raised on Long Island, and has lived for the past twenty years in the San Francisco Bay Area. She attended Wesleyan University, got a BFA in Film from New York University, and received her Masters in English/Creative Writing from San Francisco State University. She currently works fulltime in the nonprofit sector.

Christina grew up hearing stories about her Icelandic relatives and their journey to North America, following the 1875 volcanic eruption that decimated much of Iceland's farmland. To write The Tricking of Freya, she spent several years researching Icelandic history, mythology, and genealogy, including three trips to Iceland and a stint as writer-in-residence at Klaustrið (The Monastery), a stone farmhouse in a remote area, near where her grandfather had lived.

Christina’s short fiction has appeared in a variety of literary journals. The Tricking of Freya is her first novel.
