Using the discount code, you can get first-in-series books free. This includes Kiss of Fire by Deborah Cooke, The Crusader’s Bride by Claire Delacroix and Snowbound by Deborah Cooke. The cool thing about this sale is that you can then save 25% on the second book in that series. There are lots of other books too, so have a look. Remember to use the discount code.
Nook also has a reading app but this sale code (which you apply at checkout) won’t work when you shop from a mobile device or an app, just FYI.
The landing page for the Nook Book Bash (which goes through Feb 28) is right here.
