Phantom Horse 4: Phantom Horse in Danger
by Christine Pullein-Thompson
This is a great series, the author, Christine Pullein-Thompson has written over a hundred pony books and I think the Phantom Horse series is among the best of them. In the second book in the series, The family move back to England and Jean and Angus are thrilled to be able to bring Phantom home with them so their adventures can continue!. The other books in the series are Phantom Horse, Phantom Horse Comes Home, Phantom Horse Disappears, Phantom Horse - Island Mystery and Phantom Horse Wait for Me.
