How about writing a review after.....

[Silverobama]

Hi,

I bought a book for a friend's son Brian. Brian told me he was happy because he loves reading books. I really want to know how much he understands the book I gave him. I said to him:

How about writing a review after you finish reading it?

Is my italic question natural?

Yes. The rest of your English is also very good, well done.
