No, I haven't -- I picked it up in a remainder bookstore and it gave the impression it was a standalone so I thought I'd be able to cope (there were a number of other books which were obviously the second volumes of trilogies, so I gave them a miss). I realised I wouldn't understand as much as someone reading the earlier works, but I did hope he'd bring new readers up to speed fairly painlessly. But though he info-dumps like crazy, I found it all but unintelligible at the start.I hesitate to mention this TJ, but presumably you have read the earlier books that give the back story to The Technician, particularly The Line of Polity but also any of the Dragon books? Also I seem to recall it does get better once it gets swinging.
From your comment about it getting better, did you also find the beginning difficult, or just not very involving? I have got past the early bits now -- Tombs has "escaped" and the Tidy Squad woman is after him -- but I'm not finding it any easier just yet, so I really hope it picks up soon.
