Reasonably strong start in a dystopian future, but it falls apart almost as soon as they escape the city and turns into the stereotypical matemateMATE thing too many shifter romances have. The secondary romance is really freaking obvious too. I wish the author had focused more on the dystopia, perhaps having them escape INTO the city and trying to survive there, rather than copping out and going the easy route.
Also, this is a cat-shifter. CAT. Cats do not have knots on their penises, that's something dogs have. Cats have BARBS. Essentially hair that grows the, er, 'wrong' way on their penises. If you're going to include a detail like that, at least get it right! Sheesh.
