My book asks me to consider reacting 1-butene with NBS and light. 

I know that NBS and light leads to radical formation, and this is an allylic/benzylic bromination problem. 

However, my book only provides one product. 

Aren't both products expected? Actually, I would expect one product in excess (the book actually listed my minor product as the sole product). There are at least two resonance contributors, and the more major one has the more substituted radical.
