This gripping tale of twin twelve-year-olds, Verity and Ethan, who travel to Guatemala with their father, is packed full of archaeological intrigue. Whilst excavating a newly found Maya city, an ancient mask is discovered. Is the mask the cause of the end of the Maya civilisation, or is something more underhand going on? Will these children find out the answer as they deal with danger, kidnap, excitement and mystery? After the earlier death of their mother, the children have to deal with problem-solving as independent young minds in the confusing world of a foreign country. What will it take to succeed? This book melds great writing with fast-paced action and adventure, whilst also asking questions of the reader. With more than a hint of philosophy for young people, this book offers much for its readers. "Both entertaining and thought-provoking, an exciting journey through danger, and philosophy, bugs, betrayal, sibling rivalry, and an awesome archaeological puzzle." ­­ Rebecca Bradley, author of Cadon Hunter
