Well, I looked for this ebook for about half an hour, and yeah, it was totes worth it.I'd just finished Ink last night. It was really, really good. When I'd found out that there was a prequel, and it was free, I knew I really wanted to read it.It's basically about Katie and Tomo's lives before they collided. What I found interesting was Tomo's life, or should I say, point of view. I always find the guy's point of view to be interesting. Even if this is a short prequel, I'd recommend you read Ink first because these concepts can be pretty confusing.Overall, I enjoyed it! Cannot wait for the next installment in the series.
