Maybe this would be a good time to mention that when I type "not available to" I actually mean "the freebie offer is not currently available in this particular region/store that I checked, but the actual book is still for sale" (otherwise it gets "doesn't seem to exist in" or "out in a different edition/rights held by other publisher").
That said, the Kobo/Amazon US version you kindly took the time to post really isn't available to Canadians in the geo-restriction sense, since apparently the e-book rights are held by Minotaur there, but for Gentle Readers in the Commonwealth, there's a money-saving omnibus of #1 & #2 out from Atlantic/Corvus for a couponable $11 CAD at the moment:
Fire and Ice Anthology: Where the Shadows Lie / 66 North @
Kobo CA (unhelpfully and inaccurately labeled as 4th in the series)
I know what I'm going to spend my next decent-value contest codes upon if the sample reads well.
