Nick Kyme
One of the many ex-Games Workshop staff members who now works for Black Library. It would of course be completely unfair to point that Black Library does seem to hire a lot of people they already know.
Has written a lot of mediocre stuff for BL, including a series on the Salamanders and a tie-in novel for the Assault of Black Reach box set. The Black Reach novel tie-in is actually a bit of an outlier in that it's actually good. He has written almost all of the Salamanders and Salamanders-related material using his position as an editor to actively block anyone else. After all, his prize possession is a Vulkan dakimakura. He has been reviled by many fans as his work takes priority over more popular authors; Kyme’s books always get published, regardless of their quality or demand.
Though he does do some writing, it appears his main function at Black Library is as an editor, and has worked on many anthologies through the years. As such, he is thought to be the subject of much rage and hatred from an fans who quite rightly blame him for Black Library's spotty editing and the way he wilfully ignores the contributions of more popular BL authors. Thankfully he isn't connected to the commissioning process any more, and has no control over (Black Library's continuing search for new talent).
As long as his books sell reliably well and he does commit any truly grievous errors, we're stuck with him.
He is not Ben Counter.
