In another part of Harvard Square... I see that Bitterblue is among the Holiday Hundred at Harvard Book Store, which means it's 20% off.
I mention this because this is my local indie and the way to get books signed/personalized by me (before you finish your online order, a comments box will appear; please specify in the comments box that you'd like the book signed, and to whom you'd like it personalized, if anyone) -- BUT, fair warning: if you are thinking of my signed books as Christmas presents, please order before December 17, because I won't be around after that to sign them. I can't sign books from out of state. I tried once. My arm wasn't long enough.
Happy light and dark, everyone.
