When Merlin disappears, Meg races to find him in this high-spirited new instalment of Tanya Landman's much-loved horse-riding series.
Meg has been counting down the days to the summer holidays, and now they're finally here she can't wait for all the adventures she has planned for her and Merlin - picnic rides, horse shows and even a gallop along the beach!
But when Meg arrives at Merlin's field on the very first morning of the summer, it's empty. Has Merlin escaped from his field again? Or has something even worse happened?
