I read my first Ben Kane book a few weeks ago "Eagles in the Storm" and really enjoyed it. In his epilogue he mentioned Christian Cameron as an inspiration.
I just finished "Killer of Men" (Long War series) by Cameron and really enjoy his writing style. This is the first of 7 books in this series of his and I'm looking forward to reading more.
I got the first three books of this Long War series on Amazon for a couple of dollars, well worth the money.
