It was nice to get the perspective of Rives. He is the leader now, and he is more driven than ever to find answers. He is one of the ones who thinks of Nil as sentient and that Nil is calculating. He meets what seems to be a native of Nil and he has even more questions than ever. He is taking risks, following leads, and still trying to keep order in the City.
Skye is the other new character and she is actually on the outside, Her dad has been researching Nil for the longest time, based on the journals of his brother who has since passed, but was on Nil and then deemed crazy when he tells about the island. Skye has been training for the longest time, because her dad wants her to be prepared in case she is taken, and when he shows her her uncle's journals she is skeptical, but more and more begins to believe that its a real place and her dad is on to something.
This was as addictive as the first, and fast paced. I didn't want to put it down and couldn't wait to find out more about the island, and hope for the best for the characters I grow to care about who are in danger on this island with a 365 day time limit to get off or face certain death.
The build up and addition to what we know about Nil is greatly improved by Rives' nearly manic desire to find answers and push the boundaries to get those answers. Skye is hard core and the chemistry not only physical but mental compatibility and how they challenged one another and gave a new perspective to what the other has been reaching for.
Like the first encounter with Nil, we are left with hearts pounding, and the bittersweet victory dampened by the huge amount of grief for the ones who didn't make it. It's also clear that Nil's story no matter how it may have seemed to the characters, isn't over. I will def read the third book and can't wait until its out.
Bottom Line: Fast paced delving back into this beautiful but dangerous island.
