Ohhhhh that was good! A candidate for best of 2020 early in January! This book has everything : very well written, some might find it a bit prosy but I was fine with it, strong casts, and it was at it best bringing the best of every genre with a strong thriller/crime elements, hard scifi and a touch of horror. It take on the time travel/multiverse take in a very original way and just deliver a mesmerizing story that I think will stay with me for a long time. I know this author have another novel, a previous one, behind his belt and now I really want to have a look. I highly recommend reading this one!!
