I am happy to report that I managed to complete the Cadfael series by Ellis Peters today (one book left on Felse). Amazon keeps having random $1.99 and $2.99 on this and Felse series. Check DAILY for this series if you still have books to complete. Kobo sometimes matches, often not.

Today's was Dead Man's Ransom. Not matched on Kobo.
