This book was an entertaining adventure and a fitting conclusion to a good storyline.
The Troubletwister twins, Jack and Jaide, are still trying to combat "The Evil," the mysterious presence from another dimension. This is the darkest and most dangerous adventure so far with a dark tinge over much of what happens. The twins’ characters have grown up during the series and are less quarrelsome and more thoughtful, although there is still some humour in some of the things that happen and how the twins perceive them.
This story starts with a letter being found and, when it almost strangles Jack in its eagerness to be read, they realise that Grandma X’s sister, Lottie, is still alive in the realm of The Evil. She is asking for someone to rescue her. This begins a series of events that leads up to the satisfying conclusion, with both the disappearance of Lottie and what to do about The Evil being dealt with. On the way Jack and Jaide begin a series of Examinations that will bring them closer to being full Wardens, Stefano, another Troubletwister, joins them when he is sent to learn from Grandma X and Jack and Jaide are separated and have to find out about their strengths on their own and how to best use their gifts to survive.
There will be more in the series but there will have to be a slight change of direction. ( )
