The Saga of Re-Reading Epics have posted their latest podcast about the Exiles / Milieu series - 'The Surveillance' which jumps forward in time from prehistoric Europe to post-1945 America. We get to meet Uncle Rogi, hooray! He runs a sci-fi bookshop with obligatory cat, which sounds great to me. The narrators have a soft spot for him too (they call him a 'cantankerous delight').
There was once fan art of his bookstore on the interwebs once, but the website has long gone (sigh). I should have kept a copy of said art.
When I read this book, it was bundled with the sequel, 'The Metaconcert' and called 'Intervention'.

Over at Tor.com, in an article called 'Five Possible Reasons We Haven't Been Contacted by Aliens Yet', they mention the Saga of the Exiles with its explanation of 'yes, we've been visited by aliens, but it happened six million years ago in Pliocene Europe and all traces are long gone in the modern era' *
*except in our DNA
