Akiko and her crew â€” Spuckler Boach, Mr. Beeba, Poog, and Gax â€” have faced dangers unimaginable to the average fourth-grade earthling. Now their mission is finally coming to an end. At last theyâ€™ve reached the castle of Alia Rellapor â€” but that doesnâ€™t mean that things have gotten any easier. The castle is heavily guarded by robots and getting inside wonâ€™t 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 â€” half machine Throck. Can a girl whoâ€™s too scared to be school safety leader pull it off? If anyone can, Akiko can!
