As of today, Amazon is re-vamping how they catalog books in a series. They have a specific way they want the books to be listed and I have had to go and change the four books I have out in the Pierced Series so far. They no longer allow the .5s - so I've had to list ESCAPED as Book 2, which of course changes PINKED to Book 3 and PERFECT to Book 4. This is not a major change, by any means - and might even alleviate some confusion when people are looking to read books in order and not skip the novellas etc.
So in a nutshell, the PIERCED SERIES is now listed as:
Book 1 - PIERCED
Book 2 - ESCAPED (novella)
Book 3 - PINKED
Book 4 - PERFECT
Book 5 - NAPOLEON (novella coming soon!)
