This "starving" (well not quite) artist is selling signed paperback copies of her books on Ebay. You can browse them here. Including shipping to the UK, they should not be much more expensive than unsigned copies purchased through other channels.
The account is also used to sell Gothic clothing and LPs. If any of this interests you then you may wish to follow to seller profile.
All purchases are dispatched within two days of receipt of payment, and proceeds will help make the end of a difficult year more enjoyable for Carmilla and her family.
