Meljean Brooks offer Fire and Frost of free during November at Kobo. More information at her webpage.
Carina Press offers Improper Relations for free this month at their webpage.
Exclusively yours by Shannon Stacey is free at iBooks this month (No link, since I don’t have iTunes.) Samhain offers several short stories as free, some pre-orders, some permanent free reads. ( Link to Amazon, since Samhain only offers the opportunity to wishlist them at their store. Gah.)
Club Shadowlands by Cherise Sinclair is free at the moment. I like Cherise Sinclair’s Erotic Romances, but this book didn’t work for me.
Club Shadowlands is also part of Surrender, a box set featuring several popular authors. It is also free right now ( I am not getting it, since I have most of the books in my tbr pile.)
No one lives twice by Julie Moffett is free right now at Carina Press webpage. ( This is another book that didn’t work for me, but I know that it is popular. So I might give it a try again.)
