I read the second edition. It makes me wonder what changes took place apart from a new cover because my concerns seem to reflect those of readers who read the the first edition.
Disclaimer: I love historical stories and Ariel Tachna's writing. This should have been a perfect fit for me, but it wasn't
Cons:
The multiple povs gave me reader whiplash. Literally every character in a scene had their own paragraph of two. And almost every paragraph was a different pov. This made reading hard work. It also stopped you really getting to know the character. I wouldn't have objected to multiple pov if it had been restricted to a scene at a time and the five main characters.
The pining and unrequited love went on for......ever. The constant doubting and not being good enough, or being seen as hired sword/helpless child/a purse (insert where appropriate) got tiring quickly.
Even worse when they finally got together they had sex ALL THE TIME! On page, for pages and pages *yawn* Days after being released from the inquisition's clutches they were at it like bunnies. Even though Teo's back had been flayed to a bloody mess! I admit I skimmed all the sex scenes after the first; most were completely irrelevant.

Pros:
There is an excellent plot beneath all the rest of it.
I think the characters and their development would have been interesting had we stayed in their pov long enough to get to know them.

This book was too long. They should have cut all but maybe three sex scenes. The pages saved could have been put to better use at the beginning of the book, showing the journey back to Madrid and building up the trust and attraction between Christian and Teo. These are the things I would like to have seen addressed in the second edition rather than just whacking a new cover on it.
