The Invasion is the first book in K.A. Applegate's Animorphs series. Jake and his friends Cassie, Marco, Rachel, and Tobias are cutting through an abandoned construction site on their way home from the mall one evening when they see a bright light in the sky that appears to be getting closer...it doesn't take long for them to realize that the light is actually a spaceship. The ship lands and the kids get a message of warning from the dying alien who was piloting it; the people of Earth are in danger. Another alien race is working on enslaving people by controlling their minds and bodies. Until help comes, Jake and his friends may have to try and fight the invasion. To help them, the alien gives them all a gift: the ability to morph into any animal after acquiring its DNA sequence by touching it. When the kids start realizing just how many people are already under the alien control, it hits them just how in over their heads they might be.
These books were right up there with Baby-Sitters Club and Goosebumps when I was a kid; come Book Fair time, Animorphs were certainly at the top of the Want List. There is something very appealing about having the power to change into any animal at will, and to do so in order to fight for the human race would be pretty awesome. Reading it again as an adult, I realize how cheesy the writing is, but I imagine it isn't so easy to write in the voice of a pre-teen or teenager in a way that might be believable enough to keep the target audience invested in the characters - especially when the way kids talk changes so much over the years.
The characters so far are pretty one-dimensional, but there are a lot of books in the series, so there is plenty of room for development where that is concerned. There are things these kids deal with, though, that are definitely not fluffy and childish. Marco and Tobias don't have the easiest home lives, and the rest of them are about to have to grow up a lot more pretty soon here if they plan to survive the coming war until the Andalites arrive to fight the Controllers.
