I understand that Eric Nylund drops Halo fiction much sharper than one might expect, but after a youth singed by Forgotten Realms product I retain a healthy fear of the tie-in novel. Command & Conquer is the next franchise to receive the treatment, this time from Keith R. A. DeCandido - the strange force known as KRAD. I'm not familiar with the man's work, but there is rather a lot of it, and much of it tasked with distilling an existing brand into explosive paperback fiction.
