Book Meme - Day 07 - Most underrated book

This is a tough question to answer; in fact, I am not sure that there is an answer, as this is subjective to the book matter and the reader.

The success of a book is to me the following -

1. Unable to put down, and begrudging putting the book down if I have too!
2. A book where the storyline remains with me long after I have finished it
3. A book that I want to tell everyone about
4. A book where the storyline can either parallel something in my own life or that I can identify with or perhaps that I want to explore further.

Casting my mind back over the course of recent years. Books that have fitted into my own criteria are as follows

1. Home: The Story of Everyone who ever Lived in our House by Julie Myerson
2. Stasiland: Stories from behind the Berlin Wall by Anna Funder
3. The Boy in the Striped Pyjamas by John Boyne
4. A Thread of Truth by Marie Boswick
