You can buy them from Waterstones or WHSmith. You can even order them from Amazon. Co. UK. The Holiday Specials cost £5.99, while the single ones are £4.99. Note: If you are American, the Rainbow Magic book prices are different from the ones in England. From a Rainbow Magic Fan. (PS. I have got ALL the books, from number 1: Ruby the Red Fairy, all the way to 119: Una the Concert Fairy. I am eagerly awaiting for more Rainbow Magic Books to be published.)
You mean the Holiday Specials (Special Editions in the USA) The biggest books there are in the Rainbow Magic series are the Activity Books and the Annuals (Rainbow Magic Fairy Annual 2013 out now!). There might be a 2014 Rainbow Magic Annual probably out next year, but there's no information that there might be one. Just have to wait and see! :)
