Che's little sister Rosa is smart, talented, pretty, and so good at deception that Che's convinced she must be a psychopath. She hasn't hurt anyone yet, but he's certain it's just a matter of time. Che Taylor has four items on his list: 1. He wants to spar, not just train in the boxing gym. 2. He wants a girlfriend. 3. He wants to go home. 4. He wants to keep Rosa under control.

We asked Justine how she came to write a book about a child psychopath, and what the research process was like (spoiler alert: it was intense). She also tells us which other #LoveOzYA books she's excited to read in 2016.
