This 2014 there will be a lot of books that you need to stack in your library. It is pretty exciting since the dawn of ebooks, but the following list of books are those that are in print. Let us begin with The Impossible Knife of memory by Laurie Halse Anderson, it has a war veteran suffering with PTSD, a must read because the voice of Laurie Halse Anderson is very much touching.
The next book would be great as a Post Christmas read, Boxers and Saints books, by Gene Luen Yan, it is one of the best books of 2013 so this recommendation is pretty delayed. It is about the Boxer Rebellion that shows the two sides, the boxer and saint side.
For self help kinda books, because you get a moral lesson for each story, you might save these for a rainy day Ghana Must go by Taiye Selasi and Me Before You by Jojo Moyes.
