Akiko and her crew Spuckler Boach, Mr. Beeba, Poog, and Gax have faced dangers unimaginable to the average fourth-grade earthling. Now their mission is finally coming to an end. At last theyve reached the castle of Alia Rellapor but that doesnt mean that things have gotten any easier. The castle is heavily guarded by robots and getting inside wont be easy. If they do get in, they have to locate Prince Froptoppit, free him from captivity, and escape from the castle without alerting the guards or their leader, the half man half machine Throck. Can a girl whos too scared to be school safety leader pull it off? If anyone can, Akiko can!
