There's someplace, a junk store or something, where you can find old out-of-date textbooks for pennies. If you can do it cheaply, and if this fits your daughter's learning and reading styles, consider picking up some high school and undergraduate Spanish lit textbooks. Tell her any poem that she's bored by, she should just skip, or tear out and throw away.
That last sounds like heresy to me--tearing up a book?--but it's only an old textbook, and I've shredded those by the cartload (literally), so I'm a little hardened to it now. Your experiences may vary.
