A.G. Riddle has not disappointed so far. I believe this is a stand alone novel. A sci fi time traveling roller coaster ride. Story starts off with a plane crash of flight 305 in England. The survivors start off in full survival mode, finding out the strengths they never knew they had. Something wrong is in the air. Eventually they find out where and more importantly, when they are. The protagonists find themselves in a race for time to try and save the world from the mistakes they made in the past. I love how the author tells the story through two points of views of the two main characters. He even has a play with that at the end of the novel. Clever. I really enjoyed this book and I hope you take this thrill ride in your future.
