A re-read from about 13 years ago, and oddly, I think I loved it more this time around! Marsden has a magical way of describing the environment the teens are in and all of their surroundings to make it feel like you're among them, trying to survive the invasion. Even though these books are marketed towards young adults, I feel they could be enjoyed by the older crowd too. Great mix of adventure and suspense as well as a lot of funny moments of teens just goofing around like the kids they still are. From memory, I enjoyed the series even more as it went on (though I only read up to the 4th book), so I'm looking forward to reading through the rest!
