I read all of ADLER OLSEN even non-published books in France REDEMPTION read in English. I always liked: Many FILE DELIVERY .... but 64 BUTTERFLY EFFECT? ? ? ? One gets the impression that Mr. OLSEN left in a cycle of publications supported too. The idea is EXCELLENT but that length ....... is is skipping pages! ! ! I gave it 3 stars is because far M.OLSEN always kept me in suspense, but there! It starts from a wonderful idea that could have a very good novel and loses us in different circumstances that lead nowhere. I'd say if you pick a good thriller ...... go your way.
