Query: but got (a) flat

Have enjoyed previous works by Ms. J due to the pace and likability of characters. Yes-this one moves along pretty well, too, but noted a time refence flaw pretty quickly (from 8 yrs ago to 9 years ago). Did NOT see that these characters were developed nearly as well as those in past works. The kid is great at music and really good with horses and karate(with very few, if any, examples to support this). Mom is a former member of an elite team,with the love interest being the team leader. Again, very little to no support of how much butt she can kick or of how sharp this guy is as a leader. f-l-a-t
