This was one of those books I couldn’t put down. Ron Forsythe writes with clarity and power creating a novel that is truly enthralling. The central character Helen is well drawn and bears witness to an ever greater threat to the planet. The author’s command of events and creation of characters, Eunice being a fine example, underpins the catastrophic journey through hope, science and eventually despair. This is more than a science fiction novel. The characters are well created and never superfluous to the dynamic pace and plot. The writing is powerful and emotions are evoked by the credible, though thoroughly undesirable occurrences. The author writes with authority, knowledge and clarity on the scientific basis of the events and their implication. I applaud that. His empathy and passion and an ability to hold me as a reader made this a great read. I highly recommend it.
