I'm not a teacher, bookseller, librarian, or even an adult, but I volunteer at this library in Richmond over the summer, and am great at shelving, so hear me out. I loved Tigerheart so much! In some parts I wanted to cry, and when I told my dad (who is a "library clerk") about it, he smiled in a sad way that showed he understood it really well, even though he said he didn't get how it was written in a lot of different people's points of view, and sometimes like a play (He is so narrow minded when it comes to grammar) I am going to recommend it to all my friends that like adventure books and I'll read it over and over again!
