The Angel was much more deep and emotionally charged than The Siren -in a good, dark way. :)
It continues where The Siren left off. Exposes Soren's background, and after learning what I did about him, I sort of understand why he is the way he is. Soren isn't as cold and brutal as I'd thought at first. Yeah, he's Alpha, his blood roars with his Alpharism. But he cares. And he truly loves Elenor.
And then there is Michael. Man oh, I loved his HEA.
Once again, the characters are exceptionally well written with all their flaws.
Now the ending: That was something unexpected, and was torn between smiling and scowling and whooping... too many emotions at once. Good thing The Prince will be out soon.
