Booksy

Not so much a bookshop, more a website, but worth a look.

www.abebooks.co.uk is the UK branch of a website acting as an agent for indies, and other booksellers. It seems to be an advanced version of the independent site, has a more advanced shop search facility, and booksellers are able to recommend, and star rate, individual books (that's how I found it, Much Ado Books put a recommendation in for my novel). Customers who do not live near a good indie can still benefit from their stock and knowledge (the facility covers secondhand and new), and international exposure is also covered.
