I haven't been the first one to post on the 1st of the month in a long time!
I have three fiction and one nonfiction going right now. When I reach a place in one where I need a break from it, I switch over to another for a change of pace.
The three fiction books are Redoubt by Mercedes Lackey ( book four in the Colllegium series) , Mastiff by Tamora Pierce ( oddly enough this is also book 4 in a series), and Shatter Me by Tahereh Mafi, a post apocalyptic story recommended by my youngest sister. I don't usually care for this type of book but she said it was so good that I picked it up and have made it about 1/4 of the way through. It is well written but I have to read in small doses.
I am still working my way through 1000 miles up the Nile. Once again I am reading it in small doses, primarily because I am reading it in bed at night and tend to nod off after chapter or two.
