Yep, always do, didn't want to inundate and wasn't thinking through the whole universe of the audio books we've listened to at the time I posted.I highly recommend The Golden Compass, Phillip Pullman. Great cast, the voice talent that plays the main girl character just *is* Lyra to me. Excellent.
We've listened to a number of Shannon Hale audiobooks, all done by Full Cast Audio. They're a treat. Goose Girl is my primary recommendation, Princess Academy is second. I know they sound girly, but trust me - Shannon Hale is one of the best writers of our generation in terms of putting words into beautiful sentences. Love her stuff. Great fantasy with a spin.
Two of my favorite books of all time - Robin McKinley's Hero and the Crown, and The Blue Sword, are good audiobooks.
A Wrinkle In Time is read by Madeline L'Engle herself, which is neat (though her voice isn't my preferred tone for an audio talent - she was clearly older when she recorded the books, there's something special about hearing an author of her caliber reading their work, the inflections are perfect, you know what she meant to convey with the words exactly.)
Can you borrow the Prydain books from another library? Ours does a great inter-library loan, totally worth the extra waiting time to get a book/audio from another town.
We've listened to the Septimus Heap books (First one is called Magyk I think) - maybe we've done three or four of them. They are pretty good, but I don't love the storytelling (it's good, but just not my preference. Can't put a finger on what it is i don't prefer. The stories have been wildly popular.)
I do not recommend the second book in the Mysterious Benedict Society, voice talent was a gravelly voiced older male and I hated it - kept wanting him to clear his throat! He is a famous actor but I just didn't like it.
I also don't recommend the Enchanted Forest Chrnoicles in Audio - the first book being Dealing With Dragons - because the full cast used for the recording is clearly a stage cast - they projected their way right out the back speakers of the minivan. We didn't care for the style, but LOVED the books.
I've recently gushed about how much we enjoyed Howl's Moving Castle and anything else by Diana Wynne Jones. We've listened to at least 3 books of hers on audio and they're all excellent - Howl's is one of our favorites of all time.
The Percy Jackson books are pretty good in audio - narrated by a young male actor, so they feel appropriate (since they're first person stories and the boy is 12 at the start of the first book.) The first book is called The Lightning Thief. I really loved the stories, others complain that they're too predictable/overdone/etc. I think it's just a backlash, they have been insanely popular with school children for a number of years just like Harry Potter (slightly smaller scale.) The movie that was made from the first wasn't a very good reflection of the content of the book - the book is much funnier, very wry sense of humor, excellent (high) pacing. I read and listened to them all and enjoyed listening quite a lot.
I'm currently listening to Incarceron, which is a YA scifi/fantasy blend. English narrator (I know what you mean about it taking a few minutes to "tune" your ears to that particular accent) It's a very good book and has been widely talked about in YA circles. It's a bit challenging to listen to when I'm running, though, as I find my attention wanders because I'm new to running and have to focus on silly things like not falling off the treadmill. I think the book premise (an "alive" prison) and storytelling is excellent.
That should get you started.
To give you just three - go:
1) Howl's Moving Castle
2) The Goose Girl
3) Prydain Chronicles (only because you're having a hard time finding them. They're worth a #1 slot, too.)
All fantasy. Not much out there in scifi in YA (or I've been able to read those as books and not audio.) I've put down a few - The Seams being the most recent audiobook I abandoned. Just didn't get enthralled, didn't want to keep listening.
