The book was fairly good for some reason it did reminds me of Chicagoland Vampires the first book. Basically Nikki is a private investigator who is set up by one of her clients and ends up becoming an immortal(who are called Liberi) and ends up in the middle of a war between two set of immortals who are descendant from ancient gods and goddess. Now, normal humans who are descendant from a god or goddess can become immortal only if they manage to kill someone who is already immortal. It turns out that Nikki is a descendant of Artemis the goddess of hunt a rare find and therefore has to use her newly found powers to help Anderson an immortal leader of one of the group. 
 I hope in the future installments Nikki becomes more of a badass, for a opening book in the series there is definitely a promising future. At times I felt the need for more specially from Nikki since I like a good heroine, but she shows potential especially in a scene with Blake an immortal descendant of EROS where she questions him on his motives for going out with her adoptive sister. In that scene Nikki almost reminds me of Jamaal who comes of very aggressive in the beginning but we are shown better/saner side to him towards the end. I still think that there might be chance that Anderson and Nikki might have at least fling-which I thought would happen, but unfortunately that not the case for now...probably becomes he is married?? lol.
