It makes it really exciting wanting to know what happens to the Animorphs in the next book. I already have and it will be out pretty soon. Basically, it's the story of Marco's Mom, Visser One. The Animorphs show up in this one, unlike the first two Chronicles. People seem divided on this idea.
Some people hate to be left hanging.
I may do a trilogy, or I may even go with something longer. Well that's about it. Anyway I absolutely LOVE your series. Marco has his gorilla morph and a polar bear, Tobias also has polar bear, plus Hork-Bajir. Okay, lay your bets down, boys and girls.
