I recommend this book to fans of erotic historical romance that aren't too particular about editing issues.
These stories are set in early 15th Century Scotland, and blend historical detail with some fantasy elements (mythical beings and magic). Kerrigan Byrne weaves a good story, and I found this book to be an enjoyable read, but I can overlook numerous mistakes if I like the characters and the storyline.
There were inconsistencies with names and places. MacLauchlan became MacLaughlan; Castle Lauchlan was sometimes Castle Lachlan; Strathlachlan was sometimes Strathlauchlan and sometimes Straithlachlan. Lindsay Stewart became Lindsay Ross.
There were occasional goofs with tense agreement; some homophone mishaps (too/to; then/than); double negatives ("But neither had she never been happier") and a whole bunch of weirdly written sentences that would have been fine were it not for the addition (or omission) of a word. There was at least one apostrophe plural. I mention this because it's the kind of stuff that drives some readers nuts, and since she gave thanks to her editor, some people might be caught off guard by it.
I didn't catch a lot of historical inaccuracies or anachronisms. Clan colors for tartans weren't in use yet in 1411, but that's so common in books set in this period it doesn't even faze me. The women are literate, which would have been very unlikely, but I can overlook that. There were words used that didn't exist yet or wouldn't have been used in the context (especially curse words like f--ing as an adverb or adjective) but since I wouldn't want to read a book written in Middle English I let that slide.
To be honest, I was wavering a bit between giving it three or four stars, and ultimately decided to round up. If you love your romances to be extra steamy, this should be right up your alley. The sex is vanilla (no spankings or anal) but very plentiful. Byrne writes excellent love scenes packed with feeling and heat. There is quite a bit of violence, but the descriptive parts are mostly towards the bad guys (though some violence towards innocents mentioned in passing). I didn't enjoy it as much as her Victorian Rebels series, but it was well worth the money. If you have KU and aren't put off with the caveats above, I see no reason not to give it a try.
