Smashwords is having a year-end sale until January 1, and I’ve put Death at Dinner, Stabbing Set with Sapphires, and A Spartan Murder on it. They’re 75% off, so $1.25 each, so if you’ve been waiting to get them or you know someone who hasn’t read them, now’s a good time. Smashwords sells books in epub and mobi format, so they should work with whatever ereader you use. The coupon codes are right on the book’s page on Smashwords. Here are the links.
