A few minor additions which aren't significant enough to merit their own thread and will probably expire around the same time anyway:
HarperCollins-published Stephen Hunt's backlist space opera:
Six Against the Stars: Book 1.
The daily Eric James Stone short story:
Bird Dropping and Sunday: A Fairy Tale.
Kate Silver's previously-Kensington-published historical romance:
On My Lady's Honor (All for one, and one for all)
Gemma Halliday's previously Dorchester-published comedic chick-lit mystery "Spying in High Heels" (which has been freebied a couple of times previously) in another 3-novel omnibus edition with J.R. Rain and Aiden James:
J.R. Rain's Whodunnits. I've read this one and it was pretty decent. A bit over the top sometimes, but mostly good clean silly fun.
