The Comet's Curse is about a group of kids living on Galahad, which is a huge spaceship. This is their home for the next five years. But when one of their shipmates finds a stowaway on the ship, everyone goes into panic mode. The person who built the ship finds out that one of his most trusted scientists is trying to destroy the ship. When the kids find this out, they, of course, try to stop him. This ends up to be a race against time to destroy or save the human race.
This book was okay. I wouldn't be rushing to the store or library to get the others in the series. I think it was a little under-developed compared to most other series books. I think this is for elementary school kids, just for the fact that it is totally appropriate and has a series to keep you interested for a while.
