McConville's written lots that I've enjoyed, and I'm sure he'll write plenty more. But here he's up against one of the true giants of the modern prog.
Ian Edginton has created so many great series in the past two decades that it's bordering on the ridiculous. I have no choice but to vote for him, even if I fervently wish he'd get on with continuing more than a few of them before his fecundity gets the better of him again. For Scarlet Traces alone he'd beat most names on the seeding list.
