Let the Northern Lights Erase Your Name by Vendela Vida

This was a quick read, and an enjoyable one. Clarissa, the heroine, is in search of her roots. At her father's death, she finds out that he was not really her father after all, and her mother left the family when Clarissa was just a teen. She just disappeared one day when she and Clarissa were doing their Christmas shopping at the Poughkeepsie Mall. Her mom arranged to meet her at a given place at a given time, and never came back. And her father never shared this secret with her. Neither did her fiance, who has known for 15 years that it was not her father, either.
Clarissa finds her birth certificate in her father's papers after he dies and finds another man's name as her father. He is a Sami priest and lives in Lapland. (The Sami are the indigenous population in Lapland, resembling our Native Americans.) Clarissa leaves her fiance to find out the truth about her past.
When she finds him in Lapland, she finds out other interesting information as well, and her journey takes her eventually to the truth about her past.
I heard of this author because she has a new book out that is on my Want to Read list but since I could not get it, I took this one out instead. She is a good writer and I am inclined now to find her other books.
