I didn't have knowledge about the series at the time I was buying it and bought the fifth one first. I was able to catch up to the plot and read till ninth book. I just realized that there are also book 6 and half , 7 and a half and so on. So my question is, I love the series and although the books will be a out of order but should I give book 6 and half and others a try? Also books 1-5, how are they in comparison?
