While I have some gripes with this book due to its large number plot holes and scientific inconistancies, I did find it an enjoyable as a whole. The plot boils down to a kid winning a ticket to a future moon city where he escapes his wacky family and gets to attend a school that works alongside his interest in science. He and his friends inadvertently discover something sinaster is brewing within the moon's city when they come across an imprisioned baby alien, hidden in a secret tunnel at the lowest level of the moon. Apparently evil time consuming aliens, Melkorks, are the reason planets like Mars have no signs of life...and Earth is next on their list. Low and behold one of these evil doers has infiltrated the city and tries to destroy it. Surprise! An eleven-year-old saves the day, but not without ending up in a coma. While the author does hint that something fishy is up when the moon's president bribes him to keep the ordeal hush-hush and later reveals that he was the one with the key that had entrapped the baby alien, we're still left uncertain about what's really going on between the city's officals. The set up was basically a take on Noah's Ark, where the moon is the ark and the foretold alien invasion is the flood.
