Looks like K.A. Applegate's Animorphs series is going to be returning, with new covers in May, 2011. I remember when Animorphs first came out and were at the height of their popularity. Kids would come clamoring in on a daily basis, wondering and hoping when the next title would be released. I used to booktalk these all the time. I'd catch a kid's eye, and ask, "Ever talk to a school vice-principal, or other adult who seems a little weird, a little too formal? Well, they could be a Yeerk!" (Yeerks were the evil bodysnatcher aliens that the Animorphs fought against.)
I have to say, I do not love the new covers. The way they flash between animal and human without giving very many anthropomorphic qualities to the animals is a bit of a turn-off for me. But, I think kids will love, love, love them, because of how flashy and impressive they are. The original covers used die-cut cutaways, which rather vexingly would get torn up and ratty-looking rather quickly. I think the new covers are bound to have plenty more staying power. Vive la Animorphs!
