*spoilers from Immortal Rules. Please don't read if you haven't read the first installment!*Admittedly, Eternity Cure was not a planned read for me. I wasn't a big fan of Immortal Rules, I gave it 3 stars but it was a reluctant 3 stars because when I think back it was deserving of less because it was dreadfully dull at times and took me forever to get through. There was so much potential but it was severely lacking... in what? I can't quite put my finger on it but it could have been much better. The outpouring of immense love for Eternity Cure started rolling in and as soon as I read those magical words "even better than the first" I knew I had to give this one more chance. For those of you, like me, who weren't in complete love with Immortal Rules I suggest you check this installment out. It's not perfect but it's immensely more exciting.The story picks up right where Immortal Rules left off: Allison has continued her quest to free Kanin after leaving Zeke and the rest of the human group in their new home, Eden. After teaming up to save their master, Jackal and Allison set aside their differences and join forces against the much imbalanced Sarren who has captured Kanin after a many years long grudge. Jackal and Allison were quite the pair. Definitely entertaining, these two together really added some much needed humor to the story that made me love it infinitely more than the first. And I can't even begin to explain to you the excitement. This for me, was the best part of the whole thing. My biggest complaint about Immortal Rules was the parts that dragged on for far too long. With Eternity Cure, it was non-stop excitement and there was always something going on. This was truly an edge of your seat thriller and there were twists you will not see coming and turns that will leave your jaw on the ground. The relationships... for me this was a huge flaw in Immortal Rules. I never quite understood Allison's need or desire to continue staying with the human party despite their ongoing terrible treatment towards her (despite even knowing she's a vampire) and her ongoing blood lust which made it extremely hard to travel with them. The relationship with Zeke was so touching and sweet and really made Allison's ongoing desire to remain human make complete and utter sense. To me, this is what truly sets this series apart from the rest of the 'typical' vampire stories. Allison has constantly struggled to retain her sense of humanity and still has a desire to remain a 'decent human being' minus all the feelings of entitlement like her brother Jackal has. She doesn't feel she's better in any ways to the humans and wishes to be like them but has no way of ever making this a reality. Her feelings were true and something that I could completely understand and empathize with.And guys.Yeah, seriously. That ending?I have to wait how long to find out what happens?Cliffhanger... yes. Mind blown... yes. Well worth it... definitely yes. This is one thrill-ride of an installment you won't want to miss.
