Ellis Peters is the well–known and highly regarded author of the Brother Cadfael series. The novels were made into a televison series starring Derek Jacobi. Many of these books are now on sale for either $1.99 or $2.99. I’ve copied some covers below but there are even more at the bargain price right now. I have not read Brother Cadfael books yet but am about to purchase a few!
Note that the author has also written the Felse series which is a series of contemporary police procedurals with recurring characters. I have blogged on these previously. So…two good series from one excellent author!
