FYI - my books come from a variety of sources including PBS, yard sales, Salvation Army, friends and family. My own home is non-smoking, but books may have previously been read by smokers. I also have 2 cats who love to "help" me read. If you have concerns about potential allergens please feel free to PM me. *****Sale all trade/mass market paperbacks 3/1 or 8/2. Hardcovers 2/1 or 5/2.
