I haven't heard of one, so I'm not sure there is a Time Lady book. I've only read about the early episodes, the Black and White ones, from way back in the early days of Doctor Who. I read that the Time Lady there would change her look often, but it was considered a real regeneration.
In the earliest episodes she's shown. There's an episode where she "regens" slightly to change her physical form. She chooses the form of some planet's princess, but then gets mixed up with her. Chaos ensues. xD
lol...i was thinking, "maybe my hair could be a bit curlier in this pic, but come to think of it, it's not that curly lately," so it's a more true reflection So yeh, it TOTALLY looks like me, all in the long brown skirt and all - (it's my new DevID) THANK YOU!!!
