More weekend reading

Started Heresy: An Historical Novel, by S.J. Parris, this weekend.  Right off the bat, it took me a while to get into it because the back - and sometimes front - of my mind was arguing over if "AN historical" is grammatically correct or not.  I feel like it is not, or at least that "a historical novel" would be fine, but who knows.  I pronounce the H in "historical" but maybe other people don't?  Book itself is fine; main character is Giordano Bruno, so that's interesting, and it takes place during his visit to Elizabeth's Oxford to debate Copernican theory, while secretly holding a commission from Walsingham.  Not super grippping, but enjoyable.  Which is a d**m good thing, because, of course, I went and bought it on impulse the other day, because I had a 40% off coupon from Barnes & Noble - great, except it still ended up being like $15, so I had better enjoy it!  Especially considering I have literally shelves of books I mean to read at the apartment...
