If you’re at Goodreads and you haven’t read Semiosis yet, here’s your chance to get the book for free. Five copies are up for grabs. Giveaway closes June 6. Limited to United States. Sign up here.

Semiosis is included in the article “The Best Science Fiction Books About Aliens” by Jamie Green posted this month at Five Books.

Meanwhile, my latest book, Dual Memory, goes on sale today! Available in hardcover, ebook, and audiobook at all major retailers, and if you buy the hardcover book from Volumes Bookcafé, I can autograph it for you.

If you’re in Chicago, I can autograph it in person for you tonight, 6:30 p.m., at Volumes Bookstore Café, 1373 N. Milwaukee Ave., in the Wicker Park neighborhood. I’ll be chatting with Richard Chwedyk, another science fiction author and an entertaining raconteur. It will be fun.
