There's not really much to say...
I have always been a fan of Gemma's - and who can blame me; she is absolutely stunning, and is a decent singer to boot! I too had her calendar from last year, which as already mentioned was pretty much just all bikini shots (which was fine by me), but this years has much more variety and it looks like more effort and thought has went into it too. It also feels and looks slightly better quality than last years as well.
Being what it is (a scantily clad lady), it's not going to be for everyone. But if you are a fan and have a spot on the wall for it, then get it!
