Rupert Matthews 
Wales, A Very Peculiar History [PDF ebook] 

From the Roman invasion, through tall tales of Merlin and King Arthur, and right up to and beyond the incredible power of the mining industry, 'Wales, A Very Peculiar History’ takes a quirky, sideways look at some of the slightly bizarre aspects of the home of welsh rarebit, Maelgwn the Dragon, and Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch. Featuring the full gamut of Welsh providence from the coal-mining years to its rebirth in the 1970s, this book tells a tale of ups and downs, of hills and valleys, and of hope and triumph against the odds, with a few leeks thrown in for good measure.
