I can't recommend this story enough. But once you start reading, you better buckle up buttercup because you are in for the long haul. And you can forget about sleep! Even after the story concludes. I know I'm sleeping with the lights on tonight.
And if you have ever seen that movie, "The Visit" by M. Night, use that as a reference point. One reviewer had it right, this is definitely some "Flowers in the Attic" (insert word).
On a sweet note, I did enjoy the romance element too. I loved that it wasn't the insta love but rather a slow sweet realistic build from friendship to love. It really pulled at my heart. :)
