Aki knows he has the strange ability to communicate with animals by reading their minds, but he is about to discover that he has many more amazing abilities as an Heir to the Superior Beings. The Sphere of Time will take him on exciting travels to parallel worlds that are stuck in ancient times. At first it seems like lots of fun, but being an Heir is also a grave responsibility and Aki will have to face many cruel gods and fearsome creatures. The story is compelling and fast paced, hard to put down because at the end of every chapter you want to know what happens next. Aki is a very likable and realistic protagonist who narrates, with much spirit and humor, his gruesome encounters and life-threatening adventures.
