Gemma Halliday has been offering her "Hollywood" series for free recently (
https://www.mobileread.com/forums/sho...gemma+halliday), but I thought it was also worth mentioning that the first five of her "High Heels Mysteries" are available right now for $2.99 at both BN and Amazon.
I found these looking through the BN "Staff Picks: Nook Books Under $5" deals referenced in arcadata's January affiliate thread (post #136 of
https://www.mobileread.com/forums/sho...163427&page=10) if you want to use that link and give arcadata the thank-you "tip". I thought it was worth putting a bit of extra attention on this set, since I think $2.99 for the five books is a good deal, even if you already own one (like I did) or two. Arcadata indicates that the books have been price matched by Amazon and gives a link for that too in the same post.
If you don't want to use arcadata's links, you can also just search directly for High Heels Mysteries Boxed Set and it pops right up on either website. (Ignoring the oddity of a "boxed set" of e-books...
)
