Mark Anthony's books of 'The Last Rune' are all well written and cover angles of SF Fantasy that I've never read before.
In addition to the strong story line, the Author's handling of the relationships and sexual dynamics of the main Characters (Greek historic references aside) is something that I've never come across before and adds a real depth to the characters that I hadn't even realised was missing from other books I've read.
After reading Beyond the Pale, I imagined that i 'knew what was coming' but each subsequent book takes you somewhere completely unexpected and new. Put your preconceptions of SF and Fantasy characters aside when you read these books because Mark Anthony is re-writing the rules as he goes and he's doing it well.
The first book in this series, Beyond the Pale was released in 1998 and it's been about one book a year since then. As a heavy reader this means that, no matter how good a book is, I've often forgotten half the plot by the time the next book is published.
Unless you don't read a great deal or you're willing to go thought the previous books each time a new one is released, you may want to wait until the series is finished before you start on these as they rely pretty heavily upon your familiarity with the rest of the series.
