I've got another book out. You can get this at your local comics store
or on Amazon.co.uk
Nikolai Dante: Hero of the Revolution is the 10th volume ( from an eventual series of 11 from Rebellion Editions)
There is now an American edition of the first book , from Simon & Schuster.
It isn't clearly marked on Amazon which order the books come in, so...
1 - Nikolai Dante : The Romanof Dynasty ISBN-13: 978-1401203955 ( US edition Nikolai Dante : Too Cool To Kill ISBN-13: 978-1907519895 )
2 - Nikolai Dante - The Great Game ISBN-13: 978-1401205812
3 - Nikolai Dante - The Courtship of Jena Makarov ISBN-13: 978-1904265443
4 - Nikolai Dante - Tsar Wars Volume 1 ISBN-13: 978-1904265955
5 - Nikolai Dante - Tsar Wars Volume 2 ISBN-13: 978-1905437245
6 - Nikolai Dante - Hell & High Water ISBN-13: 978-1905437597
7 - Nikolai Dante - Sword of the Tsar ISBN-13: 978-1905437696
8 - Nikolai Dante - The Beast of Rhudinstein ISBN-13: 978-1905437924
9 - Nikolai Dante - Amerika ISBN-13: 978-1906735128
Most of the books are no longer easily available from Amazon.com. So it's worth trying Amazon.co.uk
However I'm told that book 3 'The Courtship of Jena Makarov' is now very hard to find everywhere. Hopefully if the new US edition does well then that book will be released in the US too.
