By the way let me start with the teams : Team Aiden....

When Alex becomes an Apollo she will be strong enough to kill even the gods themselves and they are afraid of it so she has to find a way to learn to control her powers. She has to choose in whom to trust and who to kill....
I cannot describe this book because it's that fantastic. Nobody can be trusted and we are faced with a very undecided Alex that has to choose who will stay by her side and help her with her awakening. The thing is, Seth is being very mysterious and hiding things from her and Aiden just pulls apart every time.
 We are introduced to the world of Appolyons where you get to know they're story a little better and have all your doubts cleared. Do not expect Alex to awaken before the book you have to be prepared for all the twists and very rocky ways this book tell it's story trough tough. so much information is delivered to us in this mere 330 pages because you will have to have at least one time out every time this happens.
All the characters are introduced to us in a more intimate ways, you will get to see each and everyone personality and understand they're actions better. Aiden's brother is someone that will appear a lot during this story and we will see a tremendous improvement in the way we know him and even the way he's described will change because we will know his secret and believe me it's very interesting.
Also the gods will pay us a visit. Gods such as Hades, Artemis, Poseidon and at last Apollo which  stands out due to his power and envelopment in the book from the start. We get to see them as hardcore badasses oddly normal and modern.

Slowly, I reached over and poked his arm. It felt like real flesh, warm and hard. Disappointed, I poked him again. I was expecting something amazing—celestial—by touching him. Instead all I got were weird looks from everyone in the room, including Apollo.

 “Artemis, that wasn't very nice.” Hades snapped the arrow in two and tossed it aside. “You could take an eye out with one of those things.”

Everyone that misses Caleb don't worry he is going to pay us a visit in the book as well:

“Wait. You play Mario Kart with Hades and Persephone?”

The relationship with Seth it's awful because deep inside she is only with him due to the bond but i truly believe he likes her which is bad to see and i kind of felt pity for him trough the book. Not any more. Now i just think he is an idiot that let himself be taken by the power inside of him and the one he will get from Alex. He doesn't understand anymore the right from wrong and for who is supportive of him will have a meltdown by the end of the story.  But the way he developed was amazing you see all the mood swings from the angry  Seth to Funny or cold even.

“You don’t know what’s it’s been like. To feel your power and mine together, to know that it will only grow stronger. It’s the aether, yes, but it’s also the akasha. It sings to me like a siren.” Seth.

Aiden is the contrary you will see they're relationship flower but still struggling  And for all the Aiden lovers you will love him even more....

“Because I love you, we share each other’s problems. When we fight, we fight together. I’m going to be by your side no matter what, whether you like it or not. That’s what love is, Alex. You never have to face anything alone again."

---I melted after this----

If you like this gender of book this is an awesome way to go. It has everything you could want. Intrigues and fights, pissed off gods and very hot guys what could be any better?
