Goodreads Giveaways

I like Goodreads. It's a great website, a great service, and it seems to have a large and very loyal bunch of members. And so last month I tried a couple of Giveaways. First I offered five signed copies of To The White Gate to New Zealand readers only for two weeks and received 28 entries. Not many I thought. Second, I offered six -- later increased to 10 -- copies of My Marian Year to readers in New Zealand and Australia for two weeks and received 93 entries. (Better) Although I have no idea of who all the entrants were, in both cases all the winners were women. Not sure what this means. Are women more avid readers? Do women enter Giveaways more? Anyway I have decided that this giveaway promotion is an ideal way to seed my books without paid advertising and so have arranged to more giveaways starting at the end of this week. As an experiment one (five signed copies of To The White Gate) is aimed only at the USA and Canada while the other (five signed copies of The Tapu garden of Eden) is directed at New Zealand only.
