I remember that when I was a small child, my father would read to us at night, and one of the books he read was
Kidnapped. At the time, I had the impression that it was a wonderful tale. Then, a few years later, probably 5th or 6th grade, I tried reading
Kidnapped on my own, and didn't much like it. I'm not sure I even finished. The beginning was too depressing. I'm pretty sure I then re-read the book in my 20s and liked it fine. This time around, I found it to be only so-so.
The only part I actually remembered from previous readings back in olden times was the beginning part, when David Balfour's uncle tries to kill him and then has him kidnapped, so that he would be taken off to Carolina to be sold as a slave, and thereby, no longer pose a threat to the uncle's keeping all of David's inheritance to himself.
But most of the book involves David's hooking up with a Highland outlaw, Alan Breck, and their working their way south through the Highlands back to where David could get a lawyer to deal with his avaricious uncle and where Alan could escape from the "red coats". I didn't much care for the character of Alan Breck. He was supposed to be a swash buckling romantic character, I suppose, but I found him childish, egotistical and tedious. David was by turns overly gullible and overly wise. I dunno, this didn't do much for me. YMMV.
