I actually read Lireal first (it was on a reading list) but it didn't actually ruin reading Sabriel for me ^.^ (which I read next) and then I finally got Abhorsen from my City Library ^.^ (as opposed to school...)
I loved how they ended it, but yet it also frustrates me. It
could have another book added, yet there most likely never will be. (I hope that made sence
)
