In this fast-moving, quite complicated thriller, Barclay comes roaring back on form after a couple of lacklustre efforts. I really empathised with Mike, one of the main characters. His frustration at his illness and his determination to 'do the right thing' were portrayed consistently and empathetically. In fact, all the characters were well-rounded, even those with a smaller part to play in the story. It was a quick and easy read and left me longing for just a little more story, but there was still room for a couple of decent twists and a satisfactory ending. I voluntarily read and reviewed an advanced copy of this book. All thoughts and opinions are my own.
