Although I really do not like the term, Regeneration definitely fits into the 'cozy' horror category. Our main protagonist, Joyce Lackey, is a classic baby-boomer, who starts the novel as an executive at an advertising agency where she unfortunately hit the 'glass ceiling' and now has to accept a forced retirement. In her 50s (this was first published in 1999), she is despondent, never really saving anything and now out of work. On the verge of suicide, she receives a strange call from a company called X-Gen about a job offer. X-Gen is not your typical headhunter, however, for they specialize in 'recycling' boomers into gen Xers.
The process is pretty cool; Joyce becomes part of a group who takes an intensive course in 'modern' cultural references, etc., so she will be hip to the latest trends. Then she undergoes some radical plastic surgery that makes her look at most 30 something and she has to take a special pill that will keep her skin supple and smooth-- no wrinkles here! So, after 6 months of 'coaching' and reshaping, she lands her new job at a different ad agency, this time in LA instead of Chicago. Joyce, now under her new name Joy, is ecstatic! So what if she has to pay X-Gen half of her salary? She is back to being on top of the world! Maybe she should have read that contract with X-Gen a bit closer...
In a way, this book rests upon the Boomers/X-Generation divide and clearly, the authors are Boomers! Regeneration contains all kinds of cultural references from the 60s, 70s and 80s which is, in part, why it has such a cozy feel. This makes for a fast read, and indeed, it is pretty short for a Leisure horror novel. Clever story, but not really something that will stick with you for any length of time. 3 boomers!
