Personally I thing the writing and the imaginative storyline is her best work even though it's not as well known as her twilight series. The intrigue and suspense are riveting, and it's so easy to become attached to a majority of the characters, especielly Wanderer, (aka Wanda) Jamie, Mel and Jarod. It's a great idea about humans overcoming the worst odds, and their ability to adapt even in the face of being wiped out by an invasive alien race.
