Obviously trying to target reluctant readers with high-interest topics, this series seems to be more about marketing the substance.  This is the third one in the series that I have reviewed, and like the others, there’s much attention given to dramatic images and fonts, and just a little, relatively shallow, information (okay, I did learn that the legend of the Loch Ness monster has only been circulating since the 1960s, and that oarfish can be 50 feet long).  I guess it’s not bad for what it’s trying to be, but I think there’s better available.
