From the inside of the dustjacket:
What happens when a boy mathematical genius with a computerlike memory finds himself a target of unknown murderers?
Like anyone else, he runs!
But Ronnie Cleveland can count the people he trusts on one finger. And that one, a strange girl named Ana Maria Rosalita, has more than enough troubles of her own.
In Puerto Rico, Ronnie finds Black Luis, another fugitive, and a most unusually ally, Marlowe. Together, they rescue Ana Maria Rosalita from her half brother's fortress. With relentless pursuers closing in one the runaways, Black Luis suggests one lonesome place where they can be safe. Marlowe goes there often and returns with huge mangoes that are truly "out of this world."
But is it a one-way trip? Ronnie's equations leave some doubt. Such a place is possible, yes. But to go there and return...?
Then suddenly -- time runs out. The fugutives no longer have any choice. It must be the lonesome place -- and at once!
