Once in a while my publisher will put one of my books on Kindle promotion, so they’re reduced in price to $1.49 or so. There’s another coming soon, and if you want me to email you when this happens just send me a message here and I’ll put you on a mailing list. I won’t email you about anything else but book offers and obviously I won’t give your email address to anyone else. (I wrote the books to be sort of ‘Horrible Histories for grown-ups’, and I think they should be around $3.99 or $4.99 on Kindle, but the publishers disagree and I have no power over the issue.) 

What do you think?
