We're thrilled with this monthly series - What's On Your TBR Pile? - with some of our favorite authors! TBR is "to be read" and we all have stacks we know we can't read in our lifetime. But, with a little help from our favorite authors, we can refine or (goodness!) add to our piles. Today we hear from author Sarah Penner, author of the fabulous "The Lost Apothecary". Wonder what she's read and loved lately? Join us!
