Bottom line: I recommend this book.
Why this isn't a 5-star book, I'll explain. I felt the author skimped out on the variety of god descendants and characters she could have provided. I mean, come on! The first book has three death gods and the second book introduces a fourth. How about Susanoo, the Japanese Storm god, or Enkimdu, the Sumerian god of farming? Okay, I realized the enemies are specifically Greek Gods, but only three were introduced (Artemis, Zeus, and Eros) and one mentioned (Apollo). If I forgot someone, you can tell that weren't that important.The Hindu death goddess Kali didn't even get any background information, like somehow all Americans knew about Hindu gods and goddesses. The Germanic war god goes unnamed. We have one Norse god, Loki and that about sums it up. Maybe Jenna Black centered on what she knew and focused on that, but there's so much she could have done with the world she created.
I must admit that the characters we were given are well-developed with still some mysteries yet to be unraveled. Nikki is very real with strengths and weaknesses; though I don't understand that if she's so good at finding stuff and people, why isn't she more confident about it? Rather than modesty, its like she doesn't believe it really exists. "She's a loner who feels lonely" is how I would describe her. As the main character, Nikki Glass fails to capture my heart and she remains neutral. On the other hand, I love Blake, the descendant of Eros, he made this book more entertaining. He truly resembles the god Eros (I recommend you read/look up the story of Psyche.)
The action and fight scenes were well done, with no censorship. This book is definitely NOT sexist and not afraid of brutal violence. I literally flinched sometimes as I read. Its like a harsh reality slap to the face...which I kind of appreciate. I'm into dark humor and the like.
Maybe it's the reading level, but everything Nikki thinks and does is thoroughly explained like we must understand where she is coming from because she is most definitely a good guy. I wasn't a big fan of that. And the big reveal about Artemis is that she's a MOON goddess? Not something like Zeus, her own father, basically raped one of her fellow virgin hunters? Or how Hera tried to prevent her and Apollo's birth? Something that would not pop up first thing on Google? Maybe I'm asking too much, you decide.
I would say that Jenna Black did very good with what she give us, but missed out on variety of gods present in our world and details we might not have known about gods that were mentioned. (Did you look up the story about Psyche?)
