I like Roar and Liv. 
 ...I find Roar more charming and entertaining in Under the Never Sky. Why is that, when he should've shined here? Perry was the secondary character and yet, he came out as strong as ever when he was the MC. I am so glad I loved Perry more than Roar. =) 
 Liv got spunk. That's all I can say. She's not that remarkable or I would have remembered her well. 
 This e-novella told me what a heartbreaking situation Roar was in before he was introduced in Under the Never Sky. His POV is sappy, and I think I like him better as a sidekick. .
