The Call of the Wraith by Kevin Sands

 In this forth book in the Blackthorn Key series, Christopher Rowe wakes up in a peasant's shed not knowing who he is or how he got there. The kind farmer tells him the was washed ashore after a shipwreck. As he starts to search for clues about his identity, he meets Tom and Sally, but even though they recognize him, he doesn't recognize them. They team up to try to figure out what happened, but also to solve a mystery.  Children in the village have been disappearing, and locals blame it on a ghost called the White Lady. As they investigate Christopher's past and the mystery of the missing children, Christopher's memories slowly return. 

When I was looking for what to read next, I found this book. I felt like I had read it before, but I didn't have it on my blog.  I started to listen to it, and realized I had listened to it before. It had been long enough that I didn't really remember the plot and I enjoyed listening to it again. I have really enjoyed all of the Blackthorn Key series. The characters are well drawn and the plots are clever.  I don't know how authentic the setting is, but the author does address a real middle-ages issue with each book.  This book deals with the problem of the Barbary Pirates.  I read book 3 in 2018, and I don't know why I waited so long to continue the series, but it won't be as long before I read the next book.
