Hello, thank you for your question.
Yes, a good title can help a book peak one's interest in a book; like making a good first impression.
Thus, selecting a good title is important.
No problem here.
Copyright does not protect short phrases, names, or titles (such as title of books or songs).
Trademark LAW / Unfair Competition Law
If you are going to have problems, it will be with Trademark Law or Unfair Competition Law.
Trademarks protect words, logos, short slogans and just about anything a person/company can use that will uniquely identify the source of a product or service.
For example, if your title was: "Rome for dummies", you would likely have trademark issues as such a titles implies you have association with the "for dummies" brand.
Thus, just make sure your title is not confusingly similar to a brand already out there.
IF you are going to be publishing a series of works/books, consider a unique name and register your mark with the USPTO.
If you have any additional questions, please ask.
