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...
