Sarah Hoyt has posted a short story, "Lost and Found" up at the Mad Genius Club blog, a prequel of sorts to her recently-released Darkship Revenge. Cedar Sanderson's new novel Tanager's Fledglings has been released. I haven't read it yet but plan to purchase and read it shortly. If I understand correctly, Pam Uphoff's Fort Dinosaur, the latest installment in her Directorate series, is expected to be released Very Soon.
Baen Books released the e-ARC for The Alexander Inheritance, a time travel/alternate history novel by Eric Flint, Gorg Huff, and Paula Goodlett. I read and enjoyed it, though I'm skeptical of a few elements in the story. I may review it here at some point in the future.
