Haven't ordered any books yet, but I "accidentally" bought a pair in the grocery store the other day. "Buy two for pretty much the ordinary price"...
I read the first one, The Darkest Secret by Alex Marwood. According to the jacket, a child disappears one weekend and then on another weekend the mystery is solved. Which isn't quite right. The child disappears one weekend alright. Then 12 years later her father dies and everyone who was there when the kid disappeared meets up again. But it's really only the reader who finds out what happened, through the chapters (every other) that describes what happened 12 years earlier. I wasn't crazy about the language but that might be because it was translated to Swedish and the tone just didn't work... But above all I felt the ending was incomplete, it didn't really bring "closure". I guess it wasn't really meant to, but I find it as important to me as a reader as it is to the people involved in the story...
Oh well, hopefully I won't lay awake another evening wondering why the police did such a shoddy job of figuring out what happened to the little girl...
