Airport non-choices

Since I'm flying to London this morning I thought I'd check out the crime fiction in the airport book shop and perhaps buy an impulse buy. There were two full book cases, but unfortunately very little choice. The shelves were made up of multiples of the same authors - Lee Child, Harlen Coben, Martina Cole, Michael Connolly, PD James, Linda Fairstein, Tess Gerritsen, James Patterson, Kathy Reichs, Karin Slaughter. Perhaps 50 titles between them. Nothing against these authors, but it would have been nice to have some choice and variety. Perhaps two titles per author and the books of 20 others would have help to balance things out. Surprisingly for an Irish airport, the Irish choice was limited to Tana French, Alex Barclay and Paul Carson. Given the amount of quality Irish fiction on release at the minute you would have thought the shelves would be groaning under titles by Brian McGilloway, Declan Hughes, Alan Glynn, Arlene Hunt, Jane Casey, Gene Kerrigan, etc. Very disappointing all round. Hopefully I'll get time to poke my head in a bookshop in London and pick up a couple of books.
