A TBR Jar is where you write down on small peices of paper all the books you still need to read from your bookshelves (which is a lot) in a Jar and once a month you draw a peice out and read that book. I had my son do this for me he loved it. This months pick was The Name Of The Star. So far it is really good so a good pick for the month. Wondering if I should do a TBB (to be bought) Jar? I have so many books I need to buy to complete my series and just books I have to have so this might be a way to keep me on track of what I need to buy instead of inpulse buying?
