Green Ray is book 2 in 'The Race Is On' series and follows on 6 years later from LEAP. It's another fast paced read that is jam packed with even more thrills. This time though, with the US government wanting in on the action, the door is firmly opened to political power, corruption and greed. You don't know who to trust and there is no shortage of suspense. We see Uma develop a lot more as a character and she's as brilliant as ever. I really admire Heaton's writing style and knowledge in this series, plus some appreciation to the cover theme continuation.
