It’s a form of immersive reading. I personally love it & do it whenever I can (borrowing both text & audio from my library). It helps me focus on the story. It’s fun when you enjoy the narrator in particular, which sounds like you do. Doing both is especially helpful to me for challenging books. Not saying this book will be a challenge, but remember that reading is a skill and, if you’re not in practice, it can be easy to let your mind wander.

Go for it and see how you like it! There’s little to lose.
