FROM M. C. A. HOGARTH, JIM CURTIS, KELLY GRAYSON, CEDAR SANDERSON AND OTHERS, IT’S THE SPITE BOOK:  Space Marines.

The description, from Cedar Sanderson:

 The story behind this anthology is the Games Workshop attack on the use of Space Marines, MCA Hogarth’s stand for her story Spots the Space Marine, and then the SFWA crowd’s candyass sidestepping of including her stories in the anthologies they ran to ‘celebrate’ her win of batting down the GW overstep. Ian found out about all of those things and this is his thumb in a lot of eyes…
Spite. It gets stuff done!
