Mr. Hogan did a fantastic job with the physics in this book. That is the one thing that kept me reading more than anything else. What I was disappointed in, is that fact that with a title of "Bug Park", there are so few insects/arthropods of any kind in the story, it is like eating a McD's cherry pie, and finding only one cherry...very disappointing indeed. The story should be re-titled.
Also, one point to nit-pick, for scientific names of any organism, when spelling the binomial name out, the genus is capitalized and the species is *always* lower case. On page396, "Limenitis lorquini"is what I am referring too, and the editors should be ashamed of themselves, because this is not the author's fault.
The story was enjoyable, the plot moves well, but the family structure was almost a direct parallel to Johnny Quest, including Bandit, I mean Batcat. I kept becoming distracted from the story as I read "Hoggi" instead of Taki etc., and like any good J.Q. story, the villain perishes in their own nefarious trap, leaving the hero's hands clean.
Finally, I enjoyed the little "Microcosm" joke at the end, I'm sure you will too.
