As part of an ongoing initiative Charity reviews books to save you time and teach you how to know a good book when you see it!
Charity reviews the Masterminds series by Gordon Korman. (Masterminds; Masterminds: Criminal Destiny; Masterminds: Payback)
She contrasts it to Keeper of the Lost Cities series and points out how keenly interesting (and desperately fun) it can be to allow a glaring ethical problem (cloning) drive the action of the plot and character development. Does Korman do this in an engaging way? Is it readable? Alternatively, is the problem dealt with in an ethically responsible way? Is his understanding of the Nature vs. Nurture question a reliable one?
