The writer Phoebe Morgan has set up Books for Vaccines, an auction of writing-related lots. It's to raise money for Care International's project to provide vaccines for the poorest countries.
There are some amazing things to bid for - signed books, rare editions, one-to-one sessions with editors and agents, tickets for events, etc. There are plenty of bids that are at £15 or less.
It's a chance to get a books/writing bargain, and donate to a great cause too. It closes on 21st May.
All best
Mark
