Default [Q] Android talkback for specific app

I have an Alcatel Spop
Pretty new to Android.
Downloaded a book on Google Play Books.
Started to read it OK.
Decided having it read to me would be nice.
So enable talkback in the OS settings.
Problem is everything talks back, even notifications as they come in.
So I turned it off.
Can it be enabled on a single app ??
Thanks
Jim
