The Dark Gravity Sequence #2: Island of the Sun by Matthew J. Kirby

My name is Eleanor, and the G.E.T. is searching for us all across the planet. I was able to destroy the Concentrator in Alaska and stopped it from sucking away the earth's energy and sending it to a rogue planet. However, we believe there are more Concentrators located around the world that must be shut down. These alien machines have caused another Ice Age that is slowly consuming the earth. The G.E.T. and UN have kept all this information secret from the public, and we're treated like terrorists. We've arrived in South America, but my mother is concerned about my connection to the Concentrators and the rogue planet. I don't understand how, but I'm able to sense, feel, and hear them. The G.E.T. has people everywhere, and they've captured Finn's father and brother. The rest of us are trapped under an island mountain, but we must trust the technology of an ancient culture to escape. How can our small group possibly succeed in saving the planet?

You need to read The Arctic Code before reading this one. It's nice to see the setting move to a warmer climate, as the characters don't need to wear all the heavy clothing from book one. G.E.T. is an energy company that plans to control the Concentrators and selectively decide which humans will survive, the Preservation Protocol. G.E.T. presents a formidable antagonist, and some "innocent" characters are manipulated into helping it. This situation makes readers question the motivations of new characters entering the plot. With fears of climate change in our world, this book creates a reflection of an alternative prediction for our future. It makes you think about treating nature with more respect and wondering if all the cultures in the world can unite to save it. It was clear in book one that Eleanor was different from other characters, and the mystery isn't cleared up in this book. She has a connection to alien technology, but it's not clear why or how. We also learn in this book that there are others in the world with similar connections. This book's resolution separates the protagonists once again, but I assume everyone will be happily reunited in The Rogue World, the last book in the trilogy.
