Christine Feehan is going back to her Ghostwalker roots in her 7th book in the series, "Murder Game."  Our hero is Kadan Montague (or Kaden Bishop, as he introduced himself in "<a data-hook="product-link-linked" class="a-link-normal" href="/Mind-Game-GhostWalkers-Book-2/dp/0515138096/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Mind Game (GhostWalkers, Book 2)</a>." Now, he says Bishop is just a nickname. And we need to ignore the fact that the spelling of his first name has changed over time. But I digress.) Kadan is Special Forces soldier who has been psychically and physically enhanced by evil genius scientist Dr Whitney. He is part of the first team of these soldiers, who call themselves Ghostwalkers, that were featured in the first three books.
