It's about Veronika, who actually had an almost perfect life but decides to end her life by by ingesting too many sleeping pills. She was too close to death. Her plan fails and she wakes up in Villete, a mental hospital in Slovenia, where she is told she has 5 days to live. There, she met Zedka, who has clinical depression; Mari, who suffers from panic attacks; and Eduard, who has schizophrenia, and with whom Veronika falls in love. Loads of things happened to here as well as all the residence of the Villete. Suddenly, towards the end, Veronika realised that she actually wanted to live.
I would say the book is a bit mental (well, it a story about mental people anyway) but it's a good read indeed. :D
I'm now trying to read - A Place Called Here by Cecelia Ahern.
