I was looking for a different book at the library, and found this on the same shelf. I gravitated to the word "gift" (I always think of the Magi) and picked it up. Turns out that is classified as a self-help / motivational book. If you are familiar with the children's 'Magic Tree House' series, it is kind of like that (incidentally, this is suited for children from middle school onwards), whereby the protagonist goes back in time to meet famous historical figures, and learn inspiring and life-changing lessons from them.
