Tom experiences many space adventures with his grandpa. At some point, grandpa starts to behave strangely: he yells at Tom for no apparent reason and seems to be lost in his own home. Tom's parents say that Al Tsoy Ma is to blame. This Al Tsoy Ma must be quite a nasty character. When grandpa can no longer live at home, Tom gathers all his courage: he wants to rescue grandpa from the clutches of the monster. With a lot of wit, charm, and action, this comic describes Alzheimer’s from a child's perspective. The story makes it clear: even a grandpa with dementia is a "real" grandpa. A brief explanatory section concludes the book.
