Everbound is the second book in the Everneath series. In the first book, Nikki Beckett was saved from the Everneath, but now she needs to rescue her boyfriend Jack who took her place. Her only hope of finding him in time is to rely on the help of Cole, the Everliving that fed off of her energy for a century.
Cole refuses to assist in Jack's rescue because he is in love with Nikki and wants her to become queen of the Everneath. He thinks she is special since she survived the feed and may be able to overthrow the current queen. He eventually agrees to help her find Jack, but his motives aren't pure.
The majority of the book is spent traveling down to the Everneath and navigating through the labyrinth as Cole and Nikki continue their search for Jack. There is quite a bit of mythology tied into the story, but there are a number of surprises I never saw coming. We learn considerably more about life as an Everliving, why they have two hearts, and what really happens when you break their surface heart. It definitely isn't what Nikki and Jack thought would happen.
What should have been a happily every after sort of ending took a very complicated turn. Of course, I knew there was a third book in the series. There was no way everything was going to tie together nicely at the end of this book, but I certainly didn't expect the sort of predicament Nikki now finds herself in. She has a long road ahead of her and I'm pretty sure Cole is going to be even less willing to help than he was in this book.
This is a highly entertaining series any fan of paranormal YA will enjoy. I couldn't wait to see how the series would conclude, so I have already started reading Evertrue. I should have a review for you shortly.
