I'm only in the first book, but I daresay is comparable to Kate Daniel series. Although I think Curran is still more kickass.
I love reading about Merit and Ethan conversation. Honestly, I doubt Morgan serves as a love triangle, because there is totally no competition there, which I can see.
Some minor problem near the ending that annoy me though, is why did Ethan needs to be save by Merit. He is a Master Vampire and almost three century old and needs to be save by a 1 week old Merit? That doesn't make sense to me. I hope Ethan get to kick some ass in the next installment.
I'm now anxious to start on book 2.
