This book is a great fantastical adventure following Felix, a young English boy who suffers from an incurable heart disease, as he is transported into another world. This happens when he and his parents take a trip to Costa Rica to enable him to see the both the Pacific and Atlantic oceans at the same time. After he stood with one foot on either side of the divide, his disease caused him to pass out, and when he woke up he was in a completely different world, where fantasies were the truth and where truth were fantasies. After many adventure and struggles Felix and his fellows discover a way to send him back to his own world…The book is highly enjoyable and although perhaps more suited to the middle/bottom range of cool-reads, most people should like it..
