Island of the Sun

Eleanor and her friends have shut down the mysterious Concentrator in the Arctic, but their mission is far from over. The earth is still spinning out of its orbit and growing colder by the day. Their only chance is to find the other Concentrators embedded around the world and deactivate them before it’s too late.

But doing so won’t be easy. The G.E.T. has branded them international terrorists and is tracking their every move. The organization will stop at nothing to harness the power of the Concentrators in order to preserve the select few people its leaders deem worthy, and Eleanor is soon forced to ask herself whether it’s worth risking the lives of the entire human race for a slim chance to save it.

The second book in Matthew J. Kirby’s Dark Gravity Sequence is a breathless race across a planet perilously close to extinction, one that will find Eleanor and her friends questioning their connections to it-and to each other.
