Reviews

"The best so far in this Turtledove series, with characters that you care about and action that, while grim, is plausible and engaging.""--Booklist "on "The Disunited States of America""Readers nostalgic for the SF novels of Robert A. Heinlein and Andre Norton will find much to enjoy...This is a rousing story that reminds us that 'adventure' is really someone else in deep trouble a long way off.""--""Publishers Weekly" on "Gunpowder Empire"

"Turtledove has proved he can divert his readers to astonishing places. He's developed a cult following over the years; and if you've already been there, done that with real-history novelists Patrick O'Brian, Dorothy Dunnett, or George MacDonald Fraser, for your Next Big Enthusiasm you might want to try Turtledove. I know I'd follow his imagination almost anywhere."""--"San Jose"" Mercury News" on Harry Turtledove

"Turtledove excels in alternate history."""--"Library Journal" on Harry Turtledove

"Harry Turtledove is probably the best practitioner of the classic alternate-history story since L. Sprague de Camp."""--"Locus" on Harry Turtledove
