Moon Man by David Donohue
Walter Speazlebud intends to visit the Moon. Not when he's grown up; not even with the next NASA mission. No, Walter intends to use his power of Noitanigami ('imagination' to those of you who sadly lack the ability to spell, talk and travel backwards). With the help of gutsy Annie Zuckers and gentle Levon, Walter is going to travel back in time to 1969 to prove that the Moon landing happened. So what if the Moon's surface looks like the Nevada desert? So what if Neil Armstrong botched his line (Shouldn't it have been 'one small step for a man, one giant leap for Mankind'?)? Walter's beloved grandfather said it happened, and even if he is getting confused in the head, Walter's grandfather must be right. Walter is going to prove it! And if Walter can master his gift of Noitanigami, perhaps then he will be able to take his grandfather back in time, too, and rid him of his Alzheimer's.
