I was very unsure about my thoughts on BUMPED, the first book in the series, but I think I decided, overall, that I did enjoy the story. 
 So, what happened here with THUMPED? I just can't put my finger on it. The characters were selfish and irritating. The story was getting tiring and the weird bump-esque language just became annoying after a while. 
 Just stop at BUMPED and pretend like it's a cliff-hanger ending on purpose -- that'd be my recommendation, at least.
