For those of you who've been following Cathy in The National Post over the past couple of months, you'll know that Steven Beattie's review was not a strong endorsement of her work. He took issue with her subject matter, and characterized her "fictional universe" as a place where "innocence is always corrupted, and the defenceless are always prey to random acts of malevolence."
Cathy, who has written at length about the relation between humour and tragedy in her own work for the Post, has responded to his critique on her blog. If you're curious, I'd encourage you to take a look. It's heartening for anyone who's ever struggled with the difficult process of reviewing.
