I've chosen the first two books for my abc-challenge; The Clerkenwell Tales by Peter Ackroyd, and The Virgin in the Garden by A.S. Byatt. I just went to the library and chose two books that looked/sounded good. Both writers are completely unknown to me. I've never even heard about them, let alone read anything they've written.
I've started reading the first book last night, and it looks promising. It is a medieval adventure set in London.
