"Highest score for Alvtegen".
"Once again Karin Alvtegen has succeeded in creating an exceptionally thrilling novel so gripping you cannot put it down."
"A strong reading experience that will most likely yield another award for the author."
"Karin Alvtegen has once again shown that combining complicated emotions like guilt, regret and deceit with an intelligent and breathtaking plot, is an art she is the master of. In fact, she is telling about an event that occurs to many people every day, but Karin Alvtegen accentuates it and thereby she gives the reader another novel packed with suspense."
"Sometimes the word thriller is a misleading label, but when it comes to Betrayal by Karin Alvtegen, it is an absolutely correct term. It is the kind of book that you keep on reading while the creeping uneasy threat keeps on growing and making your hair stand on end. Everybody who has read Missing - selected as the best Nordic crime novel three years ago - knows that Karin Alvtegen is great at telling thrilling stories. /…/ These two parallel stories are woven to form a whole and they belong to the best stories I read for a long time. /…/ As I wrote in the beginning, it is a novel to read at one sitting. Not only for the suspense, but as much for Karin Alvtegen's marvelous language and a plot that's just cut out for a really thrilling screen version. You have here one of this year's best books in the genre, if not the very best."
"A book where the pages turn themselves."
"The new novel Betrayal is of the highest Nordic rank /…/ The unraveling is extremely clever, with unexpected turns and hair-raising suspense till the last page. Very clever and as far from the predictable as ever possible."
