"Mr. George Griffith has made himself a high reputation as an imaginative novelist by his brilliant romances, _The Angel of the Revolution_ and _The Syren of the Skies_."--_Sketch._ "This is quite as imaginative, as clever, and as enthralling a book as its predecessor."--_Glasgow Herald._ "The book is a wild one, but its wildness and imaginative boldness make it uncommonly interesting."--_Scotsman._ "The flights of fancy and imagination displayed by the author show a most marvellous power and conception."--_Aberdeen Free Press._ "An entrancing book."--_Birmingham Post._ "Full of originality in its rendition.... A marvel of imaginative strength and picturesque pen painting."--_European Mail._ "On the whole Mr. Griffith has published a work which to our mind is the most suggestive of its kind that has been published for many years."--_Admiralty and Horse Guards Gazette._ "The work hardly lends itself to critical remark other than the expression of one's appreciation of an imaginative and glowing style likely to add to the pleasure of those who enjoy purely speculative fiction. These pictures have a weird splendour in keeping with the theme, but it is natural to desire a better future for the human race than the one here prophesied."--_Morning Post._ "His theme is a more tremendous one, and the incidents of his story tenfold more terrible than even those awful battles in the former volume. There is the same swift succession of awful calamities, the same sustained interest from title page to cover, and the same thread of human love running through the narrative which lent its chief charm to the 'Angel of the Revolution.'"--_Weekly Times and Echo._ "By lovers of sensational writing, in which the scientific discoveries of the future are forecast, and intrigue and warfare related in realistic manner under conditions which now exist but in prophetic imagination, it will be warmly welcomed.... The book must be read to be appreciated. Description is impossible."--_Bradford Daily Argus._ * * * * * Transcriber's Notes Obvious punctuation errors repaired.
