How can I record an audiobook (subquestion: is this a bad idea)?

I want to plan something great for my boyfriend’s birthday. He is one of those dudes who has everything he wants and needs, and I am a very poor student, so I am having a tough time with gift ideas.

The best thing I have been able to come up with so far is to record an audiobook for him. He listens to them constantly—probably 1–3 books per week. So I was hoping to try to find a book I think he’ll like for which no audiobook exists and make a recording of myself reading it.

(1) Is this a stupid idea?
(2) Is there an easy way to do this without purchasing expensive audio equipment? I have a Macbook Pro at my disposal and not much else.
