I was worried it might be confusing and that it might make people give up before they got hooked. Thanks for letting me know that it gave you difficulties.

I tried several different things to make it evident there were multiple universes going on, but my beta reported that using italics was giving her a headache (it gave me one as well) so it was down to colours and fonts.

Is there anything you can think of, as a reader, that would have made it less confusing? Should I have written an intro that gave more explanation?

Aside from that - thanks for your comments! I am very happy to know that you enjoyed it. Radek is just a wonderful dash of fun and flavour, isn't he? I don't know what possessed me to add him in there, but I think it made for a better story.

And yay! I'm happy to know the sprinkling of McShep was just right - of course it was McShep because I love the boys loving each other - but the story wasn't really about their relationship, it was about this thing happening, and alternate universes and Ancient tech and saving the day.

Thank you kindly for your comments!
