When Alfie and Angel Young arrive at Parkway
Grange for the Easter holidays they are introduced
to Mylor - a magnificent, unbelievable giant of a
horse with a very special secret. For Mylor is an
electronic miracle. A horse built by an eccentric
Professor for the purpose of winning the English
Grand National. Powered by the sun's rays and
perfect down to the last detail, Mylor has ten times
the strength of any living horse and a specially
designed interior which allows him to be controlled
by the children.
An adventure crammed full of excitement soon
follows, and as the story races towards its
supercharged climax it is obvious that someone
will stop at nothing in their efforts to destroy Mylor.
Suddenly a new undreamed-of nightmare faces the
children, and then everything depends on the instinct
and love of The Most Powerful Horse in the World . . .
