Please pass them on! Either to a friend or charity is fine (would prefer they didn't go to British Heart Foundation though, I'm not a fan of the way they cut up live animals). Would rather someone else read them. They'd just sit on my shelf, I rarely re-read books.
Bump for my secondhand books available for swaps. See pics ^. Otherwise they are going to the charity shop.
@ltc do you want the ones we swapped back, or are you happy for them to go to charity?
