There are some great books their, I have too many favourites to mention so I wont.
I have been in Thailand over a year and travelling in between but the best bookshop by far I have found is located in the ground floor of the guest house I use as my base, Canterbury Tales Cafe Guest house & Bookshop.
They have a great idea with the exchange scheme and you can trade any books from anywhere, they either buy them or you can get credit from your books for their books and trust me they have over 30,000 to choose from.
So if your in Pattaya any time drop in and exchange some as I might spot them and I may not have read it, I was in there today Ironically and the Author of Private Dancer, Stephen Leather came in as he is a Pal of the owner and done another book signing in the shop.
Dave the owner said he comes in occasionally so a great time to be there, Dave showed me a vid of the last time he was in there as he interviewed him.
