After doing a study and determining that $4.99 was the best price for Shooting Star, today I realized I had listed it at $5.99. I was so excited to get it released, I worked far later into the night than I should have and mis-typed the price into not one, but all three platforms (Amazon, B&N and Smashwords).
The book might be unavailable for a bit as the correct price goes into effect. My apologies for anyone inconvenienced by this.
Lesson learned: wait 'till you're rested before uploading new books.
