French isn't my bag, and others will be able to advise you on suitable books, but I can recommend using a French meetup group if there's one in your area (search
www.meetup.com). These meetups are typically attended by several native speakers who are keen to help those studying the target language. You'll probably also find people in the same position as yourself along with others who can give good advice on making progress in your studies.
One thing you could try is French comics. The pictures give you all the context and make it very easy to work out the dialogue, you'll find them on
eBay or amazon.
Good luck, a second language is a fantastic thing to have.
