The 'Dark Star' audio book is just under an hour worth of listening time and is available for .99c on Teachers Pay Teachers as well as Audible for $4.56. Unfortunately I am not able to set the audible price any lower, but the direct download from TpT is a great option for schools and educators.
From time to time it'll pop up under the middle grade tab for free.
