I've really been in a book rut lately. I either put myself on the Hold list at the library for bestsellers (which may take a looong time), or try to purchase books when they're on special for $2-$4 via Amazon. I just tried The Ninth Wife, which was disappointingly bland, and The Other Wife, which was compelling but also fell short for me.
I did pre-order the Harry Potter and the Cursed Child script, which comes out in July. Looking forward to that!
