If you're uncertain about the paperback, the ebook is as cheap as chips. (store links here) Haha! It's only $1.99 in the US and $4.99 in South Africa. (It's going for 1.28 in the UK.) You can also read some reviews on Amazon, Goodreads or on my website.
Thank you for your continued support and enthusiasm for this trilogy. I just heard from someone I've never met this morning that she's addicted to the books. That's an amazing compliment and it just about made my day.
