The Girl on the Train

The imaginative girl, Rachel, on the train dreamed of a story of a perfect girl Jessi/Megan while Rachel's life was crumbling around her. When Rachel discovered something different about Jessi one day, her last glimmer of hope was shattered beyond repair.

Told in the perspective of three main characters (Game of Thrones style) whose lives intertwined each other, mixed with two halves of the story progressing in parallels, filled with nothing but despair, in a gloomy set-up of sub-urbs of London, it's not a wonder I took as long as I did to finish up to half the book. At that point, subtly placed foreshadowings had given me an inkling of the end that I finished the rest of the book just in one evening with the purpose of simply confirming my theory.

All and all, I find the read morbid and thrilling at the same time.
