Song of the Lion is the third in Anne Hillerman's continuation of her father's Leaphorn/Chee/Manuelito series. It dropped to $2.99 a couple of years ago, and since then has briefly been on sale for $1.99 a couple of times. It is on sale again today at $1.99 at both Kindle and Kobo US.
Often continuation series are sort of so-so, but I've enjoyed all of the Anne H titles that I've read.
If you might be interested and haven't grabbed it, do it quick - previous price drops have been brief!
