This one was a reread. I often read these books as a kid, in addition to the Song of the Lioness and Immortals series. The Protector of the Small books weren’t favorites back then — as the Song of the Lioness books were — but I enjoyed them too.
Protector of the Small, book 1
The Protector of the Small books, of which this is the first, are set in the same world as Pierce’s Song of the Lioness and Immortals series — Tortall. However, the stories take place after the Immortals War (in the Immortals series) and instead focus on Keladry of Mindelan, who goes by Kel for short.
