I finished The Disaster Artist: My Life Inside The Room, the Greatest Bad Movie Ever Made by Greg Sestero the other day. I very highly recommend this book, it gives a rare insight into the otherwise unfathomable workings of the mind of Tommy Wiseau.
Also today I stayed up much later than I should have and finished The Cuckoo's Calling by JRobertK GalbRowlingaith. It was amazing! This should have been JK's first non-Potter book instead of The Casual Vacancy. Not to say TCV wasn't good, but I think maybe it was a bit too different from what readers are used to from Rowling.
