After escaping their troubles at home, Alvin and Jenna believed they were safe. They hadn't counted on the return of Zach, ex-school bully turned murderer and his caveman army. Forced through the tunnel they find themselves back on Dartmoor - except that this is definitely not the 21st century. Struggling to understand the mysteries of the tunnel will they ever return to a safe time and place? Alvin failed to keep Miss Tregarthur's promise. Now reaching across time, it seems Miss Tregarthur will have her revenge. A violent heat came from the tunnel walls. I heard Jack shriek as his hand touched the side. 'It's the only way.' Jenna pushed us on. Tregarthur's Revenge is the second instalment in the Tregarthur's Series, but can be read as a standalone book. About this book series The Tregarthur's Series is an adventurous five-book young adult fiction series about survival and self discovery. Inspired by the dark timelessness and unpredictable vast landscape of Dartmoor National Park in Southern England, a group of school children on a hiking expedition unleash an unknown power, transporting them through time, to a world beyond anything they have experienced. Cut off from the adult world in unfamiliar environments, the series chronicles their adventures as they desperately try to return home. Each book in the series involves travel to a different time, where the group has to survive using skills and knowledge they have gained from their old life. On a journey from the prehistoric age of the Neanderthals to the 14th century Black Death; from the Convict ships of the 18th century to the more recent discoveries of Marie Curie, the group are drawn back to the strange stones of Dartmoor. In Tregarthur's Legacy, the remaining members of the group are caught up in a never ending war that is raging across a WWI stricken France. In this explosion of past events, Mellanby has yet again delivered a powerful story with themes pertinent to young adults intertwined with mystery, historical fact and adventure that has delighted his growing readership. * * * This is Alex Mellanby's second novel in the Tregarthur Series. Alex's medical career fell apart when he failed to pay his GMC registration, not necessarily a bad move for humanity. He is now writing full time. The current series was inspired by the timeless nature of walks on Dartmoor. Mostly timeless for him because getting un-lost took unimaginable time. Apart from the current series he is working on a number of short stories and very different novels. Join in on the conversation at facebook/tregarthurseries or visit tregarthurseries.com
