Just a heads up, books are a very personal gift to give. I've never had it work out. Not saying you don't know your family, but it's hard to guess exactly what types of books they like. Especially if the only goal is encouraging her to read, that book will prob end up not being touched or given away.

I've had family I know really well gift me many books over the years, since I was a kid who liked to read, and it was always something I would never be interested in.

Now a Barnes and Noble/Books a Million gift card? Those are always awesome! Even though I know it feels lame to give gift cards. That could encourage her to get into a bookstore to shop for exactly something that catches her interest, and maybe shows her a whole series or author she can come back for, even!

Anyways, I hope you and your family have a happy and smooth holiday!
