During the #20series20days thread @Cathythoughts included the oland series + having read bk1 i recalled this was on my shelf so picked it up. Absolutely loved this very creepy mystery set on a remote Swedish island where katrine and joakim plus their 2 children restore the large house near 2 deserted lighthouses. The house seems to be haunted by memories of past residents which adds to an atmospheric story + tense end. Can be rd as stand alone
