Bagpiper’s Ghost 

A boy becomes possessed by an angry ghost after a visit to a Scottish graveyard Twins Jennifer and Peter rarely get along, except when it comes to their fascination with ghosts, magic, and mystery. While visiting their grandmother in Scotland, the 2 children sneak off to a graveyard—which unfortunately turns out to be a very, very bad idea. Jennifer and Peter were hoping to see the ghost of Mary Mac Fadden, who died of a broken heart when her brother, Andrew, forbade her marriage. Instead, Andrew’s angry ghost takes over Peter’s body, and if Jennifer and their grandmother can’t get the spirit to leave within 24 hours, Peter will be gone forever!   A story rich in Scottish lore and supernatural surprises, The Bagpiper’s Ghost is a wonderful treat for young readers and for fantasy lovers of any age who remain gloriously and unapologetically youthful at heart.  The Bagpiper’s Ghost is the 3rd Tartan Magic book, but you may enjoy reading the series in any order.   This ebook features an illustrated personal history of Jane Yolen including rare images from the author’s personal collection.
