I'm giving up on Let the Northern Lights Erase Your Name and here's why

I am now tossing in the towel on Vendela Vida's "Let the Northern Lights Erase Your Name." Despite its obvious strengths - a smart and sassy tone of voice in the 1st-person narrator, Clarissa, and a reasonably well-rendered exotic (to me) setting of northern Finland, the amateur plotting and architecture of this novel finally just completely drained my interest and I have no desire to work my way to the end. As noted in an earlier post, many novels begin with fairly extreme premises - a situation unlikely to happen but possible or imaginable - but then the burden is on the writer to make us care and believe. The writer has to be a trustworthy navigator, so that the plot unfolds in a credible and satisfying manner and so that we feel we are in the expert hands of someone fully comfortable with the material, someone who will guide is safely to the end of the trail. In this novel, which begins with the rather extreme premise of a mother abandoning family 14 years back and never found, and the daughter/narrator suddenly discovering that her mother had been married before to a Finn/Sami and that her apparent father was not her birth father, gets less credible as it proceeds. What finally through me over was: Clarissa is hitching through Lapland, a woman picks her up, says, gee, you remind me of someone, you look like her, an older American woman who works in an ice hotel. Gosh, could it be Clarissa's long-lost mother? This is the author's hand pushing the plot along in the clunkiest manner imaginable. Maybe this book is for others but not for me. I have to wonder about the absolutely fawning blurbs on the jacket from some major literary figures. How did she get them? Could it have anything to do with whom she knows and with favors owed or sought? Shocking!
